Illegal immigration

In Europe, the Platform for International Cooperation on Undocumented Migrants (PICUM) launched its international "Words Matter" campaign in 2014 to promote the use of the terms undocumented or irregular migrants instead of illegal. Depending on jurisdiction, culture, or context, alternatives to illegal aliens or illegal immigrants can include irregular migrants, undocumented immigrants, undocumented persons, and unauthorized immigrants, and sans-papiers (paritcularly when lacking a permit authorizing residency). to illegals. Irregular migration is a related term that is sometimes used, e.g. by the International Organization for Migration; however, because of the word migration, this term describes a somewhat wider concept, including illegal emigration. Press Association (UK), European Journalism Observatory, European Journalism Centre, Association of European Journalists, Australian Press Council, and Media, Entertainment and Arts Alliance (AU). Most commonly they use the alternative term, undocumented immigrant. Related terms that describe actions are not similarly discouraged. For example, the Associated Press continues to use the term illegal immigration, whereby illegal describes the action rather than the person. Newsweek also suggests that persons who enter a country unlawfully cannot be entirely "undocumented", as they "just lack the certain specific documents for legal residency and employment", while "[m]any have driver's licences, debit cards, library cards, and school identifications which are useful documents in specific contexts but not nearly so much for immigration". therefore the youths are not entirely undocumented, since they are documented for educational purposes. US government Title 8 of the US Code is the portion of United States law that contains legislation on citizenship, nationality, and immigration. Defining the legal term alien as "any person, not a citizen or national of the United States", The terminology used in Title 8 includes illegal alien (33 times), unauthorized alien (21 times), undocumented alien (18 times), illegal immigrant (6 times), undocumented person (2 times), and others. An analysis by PolitiFact concluded that the term illegal alien "occurs scarcely, often undefined or part of an introductory title or limited to apply to certain individuals convicted of felonies". In the United States, while overstaying a visa is a civil violation handled by the immigration court, entering (including re-entering) the US without approval from an immigration officer is a crime; specifically a misdemeanor on the first offense. Illegal reentry after deportation is a felony offense. This is the distinction between the larger group referred to as unauthorized immigrants and the smaller subgroup referred to as criminal immigrants. Democratic Senator and Senate Majority Leader Chuck Schumer has spoken out against the term undocumented, stating that "Illegal immigration is wrong – plain and simple" and that proponents of the term were "not serious" about combatting illegal immigration. During President Joe Biden's term, government websites used the term "non-citizen" instead of "alien". This change was reversed in January 2025 after President Donald Trump returned to office. Canadian government seeker that has illegally crossed from the United States to Canada is being detained. In Canada, as in the US, illegal immigrant is a commonly used term; however, there is confusion and deep dissent among many about what the term means under the law and what circumstances, and what it implies socially. Irregular is a term used by government authorities to refer to migrants who enter Canada outside of official border crossings ("points of entry"). Entrance into Canada outside of a POE is considered unlawful but not a criminal offence, or a civil offence under the Immigration and Refugee Protection Act, SC 2001, c. 27. The government of Canada, as well as the Immigration and Refugee Board, use the term irregular to refer to these crossings. The Liberal Party of Canada and the New Democratic Party typically use the term irregular, while the Conservative Party of Canada typically uses the term illegal. The use of the term undocumented is increasingly prevalent among individual MPs and MLAs in Canada, and was also used in a NDP policy document, as well as by Ontario NDP leader Andrea Horwath in a 2018 platform document. Conservative MP Dave Epp referred to "undocumented workers" in a 2020 interview with the CBC wherein he called for an end to the use of contract migrant labour by Canadian agriculture businesses, in part because many such workers are undocumented and therefore vulnerable to exploitation and unsafe working conditions. ==Reasons for illegal immigration==

Poverty Some examples do show that increases in poverty, especially when associated with immediate crises, can increase the likelihood of illegal migration. The 1994 economic crisis in Mexico, after the start of the North American Free Trade Agreement (NAFTA), was associated with widespread poverty and a lower valuation for the peso relative to the dollar. It also marked the start of a massive swell in Mexican immigration, in which net illegal migration to the US increased every year from the mid-1990s until the mid-2000s. There are also examples where natural disasters and population growth can amplify poverty-driven migration flows. Gender violence Many leave their country fleeing gender-based violence, such as honor crime or forced marriage, especially from conflicts area. Women in illegal situations are especially at risk of sexual exploitation or rape. Family reunification Some illegal immigrants seek to live with relatives who already live in a country that they are not allowed to enter, such as a spouse or other family members. Having a family who has immigrated or being from a community with many immigrants is a much better predictor of one's choice to immigrate than poverty. and as such, asylum seekers are typically treated differently from illegal immigrants. In practice, however, many asylum seekers are subjected to exceedingly long waiting periods, isolated and unsafe detention facilities, and a high probability of being denied. This has led some authors to suggest that the ideal of asylum has eroded in recent years in the Global North. According to the 1951 Refugee Convention refugees should be exempted from immigration laws and should expect protection from the country they entered. Deprivation of citizenship In a 2012 news story, the CSM reported, "The estimated 750,000 Rohingya, one of the most miserable and oppressed minorities in the world, are deeply resentful of their almost complete absence of civil rights in Myanmar. In 1982, the military junta stripped the Rohingya of their Myanmar citizenship, classing them as illegal immigrants and rendering them stateless." In some countries, people born on national territory (henceforth not "immigrants") do not automatically obtain the nationality of their birthplace, and may have no legal title of residency. Persecution With a pattern of persecution of Christians in Iran, Iranian converts to Christianity from Islam face the death penalty. Education Families want to have better lives for their children and to succeed. The article "Learning to be Illegal" discusses the safety the children have in K-12 schooling. The children are guaranteed education in a safe environment. ==Effects of illegal immigration==

Aside from illegal immigration status, illegal immigration is related to other effects. Illegal employment The employment of aliens, which is illegal under US law, has been found to be enabled by low employer sanctions and rare law enforcement in particular for subcontractors and gig economy. The search for employment is central to illegal international migration. Exploitation of labour Illegal employment makes it easier for corporations to take advantage of wage labour. If an employer does not maintain proper safety standards, refuses to pay, or creates overall precarious working conditions, looking for remedies or redress would also mean the risk of having to disclose illegal immigration status. Employers sometimes pay less than the legal minimum wage or have unsafe working conditions, relying on the reluctance of illegal workers to report the violations to the authorities. Another consequence on labor is the lack of regulations and fairness programs leading to an increased barrier to employment for women or handicapped persons. Unfair and unjust, the exploitation of illegal immigrants' labor can go unpunished. According to data from the US Census Bureau, illegal immigrants in the United States often work in dangerous industries such as agriculture and construction. A recent study suggests that the complex web of consequences resulting from illegal immigrant status limits illegal workers' ability to stay safe at work. In addition to physical danger at work, the choice to immigrate for work often entails work-induced lifestyle factors which impact the physical, mental and social health of immigrants and their families. Slavery Research at San Diego State University estimates that there are 2.4 million victims of human trafficking among illegal Mexican immigrants in the United States. Some workers are smuggled into the United States and Canada by human traffickers. People have been kidnapped or tricked into slavery to work as laborers, after entering the country, for example in factories. Those trafficked in this manner often face additional barriers to escaping slavery, since their status as illegal immigrants makes it difficult for them to gain access to help or services. For example, Burmese women trafficked into Thailand and forced to work in factories or as prostitutes may not speak the language and may be vulnerable to abuse by police due to their illegal immigrant status. Sexual exploitation Since the fall of the Iron Curtain, Western Europe is being confronted with a serious problem related to the sexual exploitation of illegal immigrants (especially from Eastern Europe), for prostitution. In the United States, human trafficking victims often pass through the porous border with Mexico. To curb the spread of sex slavery and other predation on unauthorized immigrants, then California Attorney General Kamala Harris and Mexico Attorney General Marisela Morales Ibáñez signed an accord in 2012 to expand prosecutions of criminals typically members of transnational gangs who engage in the trafficking of human beings between the two countries. Economy and labor market Research on the economic effects of illegal immigration is scant, but existing studies suggest that the effects can be positive for the native population, and for public coffers. One 2015 study states that "increasing deportation rates and tightening border control weakens low-skilled labor markets, increasing unemployment of native low-skilled workers. Legalization, instead, decreases the unemployment rate of low-skilled natives and increases income per native." This is because the presence of illegal immigrants reduces the labor costs of employers, providing them more opportunities to create more jobs. A 2013 study by the liberal think tank Center for American Progress found that granting citizenship to people who immigrated illegally would boost the US economy: doing so would raise the incomes of illegal immigrants by a quarter (increasing US GDP by approximately $1.4 trillion over a 10-years); a 2016 study found that "legalization would increase the economic contribution of the unauthorized population by about 20%, to 3.6% of private-sector GDP"; and a 2019 working paper by the University of Cyprus found that "all types of immigrants generate a larger surplus to US firms than natives do". According to economist George Borjas, immigrants may have caused the decline of real wages of US workers without a high school degree by 9% between 1980 and 2000 due to increased competition. Other economists, such as Gordon Hanson, criticized these findings. Douglas Massey argues that developed countries need unskilled immigrant labor to fill undesirable jobs, which citizens do not seek regardless of wages. Massey argues that this may refute claims that illegal immigrants are "lowering wages" or stealing jobs from native-born workers and that it instead shows that illegal immigrants "take jobs that no one else wants". From this, it is assumed that the willingness to take undesirable jobs is what gives undocumented immigrants their employment. Research indicates that the advantage to firms employing illegal immigrants increases as more firms in the industry do so, further increases with the breadth of a firm's market, and also with the labor intensity of the firm's production process; however, the advantage decreases with the skill level of the firm's workers, meaning that illegal immigrants do not provide as much competitive advantage when a high-skilled workforce is required. Lack of access to services Illegal immigrants usually have no or very limited access to public health systems, proper housing, education and banks. For instance, the current international human rights framework stipulates in various documents that the right to health and access to healthcare is fundamental and independent of a person's legal status. However, on a domestic level, many States in Europe have established the right to health as a welfare right, making it subject to citizenship or other administrative requirements. Whether it's due to the danger behind disclosing their status or because of the inherently unfair social infrastructures, these barriers are present in all types of services, from social security to health. Incentivising dangerous migration routes in southern Mexico from Central America Each year, there several hundred migrant deaths along the Mexico–United States border are reported, as immigrants cross the border illegally. Death by exposure occurs in the deserts of Southwestern United States during the hot summer season. In 2016, there were approximately 8,000 migrant deaths, with about 63% of deaths occurring within the Mediterranean. In some regions, people that are still en route to their destination country are also sometimes kidnapped, for example for ransom. In some instances, they are also tortured, raped, and killed if the requested ransom does not arrive. One case in point is the Eritrean migrants that are en route to Israel. A large number of them are captured in North Sinai (Egypt) and Eastern Sudan and held in the buildings in North Sinai. ==Methods==

Illegal border crossing , one of several customs cutters of the UK Border Force, and capable of speeds up to 26 knots, departing Portsmouth Naval Base Immigrants from countries that do not have automatic visa agreements, or who would not otherwise qualify for a visa, often cross the borders illegally in some areas such as the Mexico–United States border, the Mona Channel between the Dominican Republic and Puerto Rico, the Strait of Gibraltar, Fuerteventura, and the Strait of Otranto. Because these methods are illegal, they are often dangerous. Would-be immigrants have been known to suffocate in shipping containers, boxcars, and trucks, sink in shipwrecks caused by unseaworthy vessels, die of dehydration, or exposure during long walks without water. An official estimate puts the number of people who died in illegal crossings across the US–Mexican border between 1998 and 2004 at 1,954. Human smuggling is the practice of intermediaries aiding illegal immigrants in crossing over international borders for financial gain, often in large groups. Human smuggling differs from but is sometimes associated with human trafficking. A human smuggler will facilitate illegal entry into a country for a fee, but on arrival at their destination, the smuggled person is usually free. Trafficking involves a process of using physical force, fraud, or deception to obtain and transport people. Types of notorious human smugglers include Snakehead gangs present in mainland China (especially in Fujian) that smuggle laborers into Pacific Rim states (making Chinatowns frequent centers of illegal immigration) and "coyotes", who smuggle illegal immigrants to the Southwestern United States and have been known to abuse or even kill their passengers. Overstaying visa Many illegal immigrants are migrants who originally arrive in a country lawfully but overstay their authorized residence (overstaying a visa). For example, most of the estimated 200,000 illegal immigrants in Canada (perhaps as high as 500,000) are refugee claimants whose refugee applications were rejected but who have not yet been expelled from the country. Another example is formed by children of foreigners born in countries observing jus soli ('right of territory'), such as was the case in France until 1994 and in Ireland until 2005. In these countries, it was possible to obtain French or Irish nationality (respectively) solely by being born in France before 1994 or in Ireland before 2005 residency, work, or citizenship rights for one or both of the spouses or other benefits. In the United Kingdom, those who arrange, participate in, or officiate over a sham marriage may be charged with several offenses, including assisting unlawful immigration and conspiracy to facilitate a breach of immigration law. The United States has a penalty of a $250,000 fine and five-year prison sentence for such arrangements. The US Immigration and Customs Enforcement (ICE) and the Justice Department say that they do not have accurate numbers on the rate of attempted marriage fraud. In the 2009 fiscal year, 506 (0.2%) of the 241,154 petitions filed were denied for suspected fraud; 7% were denied on other grounds. ==Legal Protections and Exceptions==

Not all unauthorized immigration are subject to penalties, and many countries provide legal protections or give temporary status for certain categories of irregular residents. Asylum seekers Individuals entering a country without authorization with the purpose to seek asylum are protected by international law, notably Article 31 of the 1951 Refugee Convention and its 1967 Protocol. These laws stipulate that asylum seekers cannot be penalized for unauthorized entry if they present themselves promptly and are permitted to reside lawfully until at least their cases are fully processed. Per European Court of Human Rights under the European Convention on Human Rights, they cannot be illegally returned to countries where they face persecution, torture, or inhuman treatment, under the principle of non-refoulement. However, some individuals may attempt to misuse this pathway through fraudulent claims. Family-based protections Many countries, including the US, limit or defer the removal of unauthorized residents who are close family members of citizens or long-term residents to protect family unity or prevent undue hardship. This may include parents, spouses, or children of citizens, and can allow exception from penalties and temporary legal residence or deferred removal. Temporary or humanitarian status Legal exceptions from deportation and penalties can be made for Temporary Protected Status, deferred action, or similar forms of humanitarian relief for unauthorized immigrants that arrived from countries affected by conflict, natural disaster, or other emergencies. Programs often permit such irregular residents to remain lawfully for a defined period and may include work authorization. In the US, Temporary Protected Status allows individuals who were previously unauthorized to obtain legal, temporary status but the pathway in itself does not lead to permanent residence (Green Card). However TPS holders who qualify for asylum, may still apply for asylum to attain permanent residence status. Pathways to regularization In many jurisdictions, temporary or protected residence that began with unauthorized entry can, under specific, lawful criteria, provide a pathway to permanent residency and, eventually, citizenship. This pathway is generally not automatic and illustrates that certain unauthorized residence does not necessarily equate to criminality or deportation, at least until the individual's status is fully resolved under the applicable legal process. ==By country or region==

Africa Angola In 2007 around 44,000 Congolese were forced to leave Angola. Since 2004, more than 400,000 illegal immigrants, almost all from the Democratic Republic of the Congo, have been expelled from Angola. South Africa No accurate estimates of the number of illegal migrants living in South Africa exist. Estimates that have been published vary widely. A 1996 Human Sciences Research Council study estimated that there were between 2.5 million and 4.1 million illegal migrants in the country. In their 2008–09 annual report, the South African Police Service stated, "According to various estimates, the number of undocumented immigrants in South Africa may vary between three and six million people." Other estimates have put the figure as high as 10 million. , Statistics South Africa's official estimate is between 500,000 and one million undocumented migrants. A large number of Zimbabweans have fled to South Africa as a result of instability in Zimbabwe, with many living as illegal migrants in South Africa. Sociologist Alice Bloch notes that migrants in South Africa have been the victims of xenophobia and violence, regardless of their immigration status. There are about 1.2 million Indians living in Bangladesh illegally as of 2014. By contrast, there are at least 20 million Bangladeshi illegal immigrants (20–40 times more) living in India, Bhutan Immigration in Bhutan by Nepalese settlers (Lhotshampa) began slowly towards the end of the 19th century. The government passed the Bhutanese Citizenship Act 1985 to clarify and try to enforce the Bhutanese Citizenship Act 1958 to control the flood of illegal immigration. Those individuals who could not provide proof of residency prior to 1958 were adjudged to be undocumented immigrants. In 1991 and 1992, Bhutan expelled roughly 139,110 ethnic Nepalis, most of whom have been living in seven refugee camps in eastern Nepal ever since. The United States has offered to resettle 60,000 of the 107,000 Bhutanese refugees of Nepalese origin now living in U.N. refugee camps in Nepal. The Bhutanese government, even today, has not been able to sort out the problem of giving citizenship to those people who are married to Bhutanese, although they have been in the country for 40 years. India undocumented immigrants It is estimated that several tens of millions of illegal immigrants live in India. Precise figures are not available, but the numbers run in tens of millions, at least 10 million are from Bangladesh, others being from Pakistan, Afghanistan, and others. According to the Government of India, there are at least 20 million illegal immigrants from Bangladesh alone. This makes India the country with the largest number of illegal immigrants in the world. During the Bangladesh Liberation War, at least 10 million Bangladeshis crossed into India illegally to seek refuge from widespread rape and genocide. According to Indian Home Ministry, at least 1.4 million Bangladeshi crossed over into India in the last decade alone. According to a pro-Indian scholar, the trip to India from Bangladesh is one of the cheapest in the world, with a trip costing around Rs. 2000 (around $30 US), which includes the fee for the "Tour Operator". As Bangladeshis are culturally similar to the Bengali people in India, they are able to pass off as Indian citizens and settle down in any part of India to establish a future, This obstruction will virtually isolate Bangladesh from India. The barrier's plan is based on the designs of the Israeli West Bank barrier and will be 3.6 m (11.8 ft) high. The stated aim of the fence is to stop infiltration of terrorists, prevent smuggling, and end illegal immigration from Bangladesh. Malaysia There are an estimated 800,000 illegal immigrants in Malaysia. In January 2009, Malaysia banned the hiring of foreign workers in factories, stores and restaurants to protect its citizens from mass unemployment amid the late 2000s recession. An ethnic Indian Malaysian was recently sentenced to whipping and 10 months in prison for hiring six illegal immigrants at his restaurant. "I think that after this, Malaysian employers will be afraid to take in foreign workers (without work permits). They will think twice", said immigration department prosecutor Azlan Abdul Latiff. "This is the first case where an employer is being sentenced to caning", he said. Illegal immigrants also face caning before being deported. Pakistan As of 2005, 2.1% of the population of Pakistan had foreign origins, however the number of immigrants population in Pakistan recently grew sharply. Immigrants from South Asia make up a growing proportion of immigrants in Pakistan. The five largest immigrant groups in Pakistan are in turn Afghans, Bangladeshis, Tajiks, Uzbeks, Turkmens, Iranians, Indians, Sri Lankan, Burmese, and Britons, including a sizeable number of those of Pakistani origin. Other significant expatriate communities in the country are Armenians, Australians, Turks, Chinese, Americans, Filipinos, Bosnians, and many others. In October 2023, the government of Pakistan announced a plan to deport foreign nationals who either lacked valid visas or had overstayed their visas by more than one year. The mass deportations primarily targeted Afghan nationals without legal documentation to remain in Pakistan. By November 2025, Pakistan had repatriated a total of 1.7 million Afghans. Philippines It was estimated by Teresita Ang-See, a prominent leader and activist of the Chinese Filipino community, that by 2007, as many as 100,000 illegal immigrants from mainland China are living in the Philippines, a tenth of the ethnic Chinese population. The latest influx has come in part because of Manila's move in 2005 to liberalise entry procedures for Chinese tourists and investors, a move that helped triple the number of Chinese visitors to 133,000 the prior year. Many of the new Chinese immigrants encounter hostility from many Filipinos, including Filipino-born Chinese, for being perceived as engaging in criminal activities and fraud, to being of unruly behaviour. South Korea According to the Republic of Korea Immigration Service, as of 31 December 2014, there were 208,778 illegal immigrants, which is 11.6% of 1,797,618 total foreign nationals who resided in South Korea. Most illegal immigrants in South Korea are Asian. The top 10 home countries of those illegal immigrants all came from other Asian countries with China at number 1 followed by Thailand, Vietnam, Philippines, Mongolia, Indonesia, Uzbekistan, Bangladesh, Sri Lanka, and Cambodia. Other countries • China: China is building a security barrier along its border with North Korea to prevent the refugees or defectors from North Korea. Moreover, many illegal immigrants from Mongolia have tried to make it to China. There might be as many as 100,000 Africans in Guangzhou, mostly illegal overstayers. To encourage people to report foreigners living illegally in China, for instance during the 2010 Asian Games in Guangzhou, the police gave a 100 yuan reward to whistle blowers whose information successfully led to deportation). • Nepal: in 2008, Nepal's government led by the Communist Party of Nepal (Maoist Centre) initiated a major crackdown against Tibetan exiles with the aim to deport to China all Tibetans living illegally in the country. Tibetans started pouring into Nepal after a failed anti-Chinese 1959 Tibetan uprising. • Thailand: Thailand has become a major destination of illegal immigration, especially from neighbouring countries. A law passed in 1979, a time when many Vietnamese and Cambodian people were entering Thailand as refugees, gave authorities nearly unlimited powers to detain illegal immigrants indefinitely, with few guidelines regarding the treatment of detainees. The law also requires most resident foreigners to notify the government every time they leave their permanent residence for more than 24 hours. This law had fallen into disuse but as of 2019 was revived due to a crackdown under the slogan "Good guys in, Bad guys out". Americas Brazil Brazil has long been part of international migration routes. In 2009, the government estimated the number of illegal immigrants at about 200,000 people; a Catholic charity working with immigrants said there were 600,000 illegal immigrants (75,000 of whom were from Bolivia). That same year, the National Congress of Brazil approved an amnesty, opening a six-month window for all foreigners to seek legalization irrespective of their previous standing before the law. Brazil last legalized all immigrants in 1998; bilateral deals, one of which promoted the legalization of all reciprocal immigrants with Bolivia to date, signed in 2005, are also common. Illegal immigrants in Brazil enjoy the same legal privileges as native Brazilians regarding access to social services such as public education and the Brazilian public healthcare system. An October 2009 piece from O Globo, quoting a UNDP study, estimates the number of illegal immigrants at 0.7 million, and points out to a recent wave of xenophobia among the general populace. Canada There is no credible information available on illegal immigration in Canada. Estimates range between 35,000 and 120,000 illegal immigrants in Canada. James Bissett, a former head of the Canadian Immigration Service, has suggested that the lack of any credible refugee screening process, combined with a high likelihood of ignoring any deportation orders, has resulted in tens of thousands of outstanding warrants for the arrest of rejected refugee claimants, with little attempt at enforcement. Refugee claimants in Canada do not have to attempt re-entry to learn the status of their claim. A 2008 report by the Auditor General Sheila Fraser stated that Canada has lost track of as many as 41,000 illegal immigrants. This number was predicted to increase drastically with the expiration of temporary employer work permits issued in 2007 and 2008, which were not renewed in many cases because of the shortage of work due to the recession. Chile In November 2025, Peruvian President José Jerí declared a state of emergency along the southern border with Chile to block an influx of undocumented migrants, primarily Venezuelans. Large numbers of Venezuelans attempted to leave Chile and enter Peru following threats of mass expulsion from Chilean President-elect José Antonio Kast. Mexico In the first six months of 2005, more than 120,000 people from Central America were deported, as compared to 2002, when for the entire year, only 130,000 were deported. People of Han Chinese origin pay about $5,500 to smugglers to be taken to Mexico from Hong Kong. It is estimated that 2.4% of rejections for work permits in Mexico correspond to Chinese citizens. In a 2010 news story, USA Today reported, "... Mexico's Arizona-style law requires local police to check IDs. And Mexican police freely engage in racial profiling and routinely harass Central American migrants, say immigration activists." Many women from Eastern Europe, Asia, and Central and South America take jobs at table dance establishments in large cities. The National Institute of Migration (INM) in Mexico raids strip clubs and deport foreigners who work without proper documentation. In 2004, the INM deported 188,000 people at a cost of US$10 million. In September 2007, Mexican President Calderón harshly criticized the United States government for the crackdown on illegal immigrants, saying it has led to the persecution of immigrant workers without visas. "I have said that Mexico does not stop at its border, that wherever there is a Mexican, there is Mexico", he said. However, Mexico has also deported US citizens, deporting 2,000 cases in 2015 and 1,243 in 2014. Illegal immigration of Cubans through Cancún tripled from 2004 to 2006. In October 2008, Mexico tightened its immigration rules and agreed to deport Cubans who use the country as an entry point to the US. It also criticized US policy that generally allows Cubans who reach US territory to stay. Cuban Foreign Minister said the Cuban-Mexican agreement would lead to "the immense majority of Cubans being repatriated". United States Approximately 11 million illegal immigrants were estimated to be living in the United States in 2006. The Pew Hispanic Center estimated that this peaked at 12 million in March 2007 and declined to 11 million again in March 2009. The majority of the illegal immigrants are from Mexico. The issue of illegal immigration has long been controversial in the United States. In 2007, President George W. Bush called for Congress to endorse his guest worker proposal, stating that illegal immigrants took jobs that Americans would not take. The Pew Hispanic Center notes that while the number of legal immigrants arriving has not varied substantially since the 1980s, the number of illegal immigrants has increased dramatically and, since the mid-1990s, has surpassed the number of legal immigrants. Penalties for employers of illegal immigrants, of $2,000–$10,000 and up to six months' imprisonment, go largely unenforced. Political groups such as Americans for Legal Immigration have formed to demand the enforcement of immigration laws and secure borders. ALIPAC has also called for "safe departure" border checkpoints, free of criminal checks. In a 2011 news story, the Los Angeles Times reported,... illegal immigrants in 2010 were parents of 5.5 million children, 4.5 million of whom were born in the U.S. and are citizens. Because illegal immigrants are younger and more likely to be married, they represented a disproportionate share of births—8% of the babies born in the U.S. between March 2009 and March 2010 were to at least one illegal immigrant parent. are in red, and states in gray have no official policy. Immigration from Mexico to the United States slowed in the early 2010s. This has been attributed to the slowing of the US economy, the buildup in security along the border and increased violence on the Mexican side of the Mexico–United States border. In 2016, the Library of Congress announced it would substitute "noncitizens" and "unauthorized immigration" for "illegal aliens" as a bibliographic retrieval term, saying the once common phrase had become offensive, and was not precise. However, the change was suspended and the heading "illegal aliens" remains in use. In 2018, Attorney General Jeff Sessions instructed the US attorneys' offices not to use the term "undocumented immigrants", but to instead refer to people as "illegal aliens". Sanctuary cities are US jurisdictions (cities, counties, or states) that limit cooperation with federal immigration authorities, specifically by restricting local law enforcement from assisting in enforcing federal immigration law. Local law enforcement in these jurisdictions often restricts honoring Immigration and Customs Enforcement (ICE) detainer requests and avoids questioning residents about their legal status. On his first day in office, Joe Biden halted the construction of the Mexico–United States border wall, ending the national emergency declared by the Trump administration on 1 February 2019. Early during Biden's tenure, a surge in migrants at the US border stirred controversy. According to an August 2025 Pew Research Center report, the unauthorized immigrant population grew by 3.5 million between 2021 and 2023, reaching a record 14 million. Other countries • Venezuela: an estimated 200,000 Colombians fled the Colombian conflict and sought safety in Venezuela. Most of them lacked identity documents, which hampered their access to services, as well as to the labor market. The Venezuelan government has no specific policies on refugees. A much greater number of Venezuelans entered Colombia trying to escape from the political, economic and humanitarian crisis in the 21st century, especially during the last five to 10 years. • Chile: Chile has recently become a new pole of attraction for illegal immigrants, mostly from neighboring Peru and Bolivia but also Ecuador, Colombia, Dominican Republic, Paraguay, Cuba, Venezuela and Haiti. According to the 2002 national census, Chile's foreign-born foreign population has increased by 75% since 1992. • Dominican Republic: the Dominican Republic is a nation that shares the island of Hispaniola with Haiti. An estimated 1,000,000 Haitians live and work in the Dominican Republic, which has a total population of about ten million. The percentage of Haitians that have illegally immigrated to the Dominican Republic is not accurately known, and "many Dominicans have come to resent the influx of lower-paid workers from across the border and have sought to make their country less hospitable to noncitizens." Eurasia and Oceania Australia protest in Australia with banner reading "no one is illegal" On 1 June 2013, the Migration Amendment (Reform of Employer Sanctions) Act 2013 commenced. This new law puts the onus on businesses to ensure that their employees maintain the necessary work entitlements in Australia. The new legislation also enables the Australian Department of Immigration and Citizenship to levy infringement notices against the business (AUD $15,300) and individual (AUD $3,060) employers on a strict liability basis—meaning that there is no requirement to prove fault, negligence or intention. Russia Russia experiences a constant flow of immigration. On average, 200,000 legal immigrants enter the country every year; about half are ethnic Russians from other republics of the former Soviet Union. There are an estimated 10–12 million foreigners working in the country without legal permission to be there. There has been a significant influx of ethnic Georgians, Armenians, Azerbaijanis, Tajiks, and Uzbeks into large Russian cities in recent years, which has been viewed very unfavourably by many citizens and contributed to nationalist sentiments. Many immigrant ethnic groups have much higher birth rates than native Russians, further shifting the balance. Some Chinese flee the overpopulation and birth control regulations of their home country and settle in the Far East and southern Siberia. Russia's main Pacific port and naval base of Vladivostok, once closed to foreigners, today is bristling with Chinese markets, restaurants and trade houses. Illegal border crossing is considered a crime, and captured illegal border crossers have been sentenced to prison terms. For example, Rossiyskaya Gazeta reported in October 2008 the case of a North Korean who was detained after illegally crossing the Amur River from China. Considered by Russian authorities an "economic migrant", he was sentenced to 6 months in prison and was to be deported to the country of his nationality after serving his sentence, although he may now risk an even heavier penalty there. That was just one of the 26 cases year-to-date of illegal entrants, of various nationalities, receiving criminal punishment in Amur Oblast. Turkey Turkey receives many economic migrants from nearby countries such as Azerbaijan, Georgia, Armenia, but also from North Caucasus, Central Asia, West Asia, Afghanistan and Pakistan. The Iraq War is thought to have increased the flow of illegal immigration into Turkey, and the global parties directly involved in the conflict have been accused of extending a less-helping hand than Turkey itself to resolve the precarious situation of immigrants stranded in the passage. Europe The Schengen Area is a multilateral agreement between 27 states in which they in most cases abolish the border control among themselves. These states include most of the EU countries, as well as the EEC countries Norway, Switzerland and Iceland. Any person who is physically inside any of the Schengen states will usually be able to travel to any other Schengen state without hindrance from the law enforcement, even if they have no legal right to enter another Schengen Area member state. A person who wishes to immigrate illegally to a Schengen Area member state may therefore find it more practical to enter it through another member state. According to a BBC report from 2012, over 80% of illegal immigrants entering the European Union pass through Greece. EU countries that are not members of the Schengen Agreement are still committed to allow lawful entry by citizens of EU countries; however, they may exercise border control at their discretion. Citizens within the EU is an economic and political partnership between 28 European countries that together cover much of the European continent. A citizen of an EU member state has the right to seek employment within any other member state. The Schengen Agreement does not regulate treatment of persons who enter the Schengen Area illegally. This is therefore left to the individual states, and other applicable international treaties and European case law. Illegal immigration to Schengen and to Europe in general was increasing sharply since approximately early 2014. France Children born to noncitizens in France are not immigrants themselves, but they are considered foreigners under French law, until they reach the age of 18, at which time they automatically become citizens. French citizenship is based in the idea of political unity and is a citizenship that may be more accessible than other EU countries, such as Germany and the UK; however, many French citizens feel that those who gain French citizenship should conform to the cultural aspects of French life. There were between 890,000 and 1.2 million illegal immigrants in France. French law prohibits anyone from assisting or trying to assist "the entry of a foreigner in France" (except for a non-EU national, entering in metropolitan France illegally from the territory of a Schengen country), which enabled them to harass activists helping refugees Hungary In 2014, Hungary registered 43,000 asylum seekers and 80,000 up to July 2015. The border was sealed on 15 September 2015 and the fence was the following day attacked by refugees and defended by riot police. With the Hungary-Serbia border closed, migrants then started heading to Croatia, but as Croatia led the migrants to the Hungary-Croatia border, Hungary then started the construction of a second fence along its border with Croatia on 18 September 2015. Spain On 9 October 2024, Spanish Prime Minister Pedro Sánchez urged the European Parliament to accelerate the implementation of the New Pact on Migration and Asylum to address the ongoing migration crisis in the Canary Islands. The region experienced a record influx of 46,843 migrants, primarily from Senegal, Mali and Morocco, representing an increase from 39,910 arrivals in 2023. Sánchez proposed legislation to establish a mandatory distribution system for migrants across Spanish regions to ease the pressure on the Canary Islands. Sánchez has supported policies aimed at encouraging immigration as a strategy to counteract Spain's demographic decline and aging population. In January 2026, Sánchez authorized a decree aimed at regularizing approximately 500,000 undocumented immigrants residing in Spain. United Kingdom Many try to cross the English Channel from Calais to seek asylum or refugee status in the United Kingdom. Truck drivers can be fined up to €2,500 if illegal immigrants are found on board. In 1986, an Iranian man was sent back to Paris, from London, as he was unable to present any ID to British immigration officers. He stayed at the airport for nearly twenty years and his story loosely inspired a film, The Terminal. there were between 550,000 and 950,000 illegal immigrants in the United Kingdom. The United Kingdom is a difficult country to reach as it is mostly located on one island and part of another, but traffickers in Calais, France, have tried to smuggle illegal immigrants into the UK. Many illegal immigrants come from Africa and Asia. As of 2008 there were also many from Eastern Europe and Latin America having overstayed their visas. A 2012 study carried out by the University of Oxford's Centre on Migration, Policy and Society (COMPAS) has estimated that there were 120,000 illegal migrant children in the UK, of whom 65,000 were born in the UK to parents without legal status. According to the study these children are at risk of destitution, exploitation and social exclusion because of contradictory and frequently changing rules and regulations which jeopardize their access to healthcare, education, protection by the police and other public services. The Home Office estimated that 4,000 to 10,000 applications a year to stay in the UK are made on the basis of a sham marriage. Many illegal immigrants or asylum seekers have tried to enter the UK from France, by hiding inside trucks or trains. On 11 August 2020, the Government of the United Kingdom and France worked together on a single channel to finalize a new plan for blocking illegal migrant route. Many of the migrants who aimed to emigrate to the United Kingdom came from Afghanistan, Iraq, Iran, Syria and countries in Africa, fleeing poverty, persecution or war. In 2025, a total of 41,472 migrants arrived in the UK via small boat crossings in the English Channel. Other countries • Bulgaria: in 2013, 11,000 persons attempted to enter Bulgaria via its border with Turkey. Their aim is not believed by Bulgarian border officials to remain in Bulgaria, but to go to other European countries. The numbers rose sharply with the Russian invasion of Ukraine from 57,637 entries in 2021 to 91,986 in 2022. • Italy: in November 2023, Italian Prime Minister Giorgia Meloni and her Albanian counterpart Edi Rama signed an agreement to relocate migrants to Albania, a deal criticized by International Rescue Committee and Doctors Without Borders. Italy plans to construct two detention centres in Albania which would initially house 3,000 individuals upon opening in late 2024, but could process up to 36,000 people annually once fully operational. Meloni has previously threatened immediate deportation of migrants, which is not allowed within the EU, and Albania's position outside the EU is viewed as significant in light of this. In response the European Commission requested further details on the arrangement for scrutiny. • Norway: the number of illegal immigrants in Norway was estimated to roughly 20 thousand in 2009, and to between 18 and 56 thousand in 2017. Estimates by organizations working with illegal migrants are much lower, between 5 thousand and 10 thousand in 2011. • Switzerland: it is estimated that at least 100,000 individuals reside in Switzerland without being registered with the authorities and thus are considered illegal immigrants by the state. Many are also workers, employed as nannies, labourers on farms or construction sites, as well as waiters or kitchen or other ancillary staff in the restaurant and hotel industry. Middle East Iran Since late April 2007, the Iranian government has forcibly deported back Afghans living and working in Iran to Afghanistan at a rate between 250,000 and 300,000 per year. The forceful evictions of the refugees, who lived in Iran and Pakistan for nearly three decades, are part of the two countries' larger plans to repatriate all Afghan refugees within a few years. Iran said that it would send 1,000,000 by March 2008, and Pakistan announced that all 2,400,000 Afghan refugees, most living in camps, must return home by 2009. Aimal Khan, a political analyst at the Sustainable Development Policy Institute in Islamabad said it would be "disastrous" for Afghanistan. Iran plans to remove two million undocumented Afghan migrants by March 2025, with authorities reporting a rise in arrests and voluntary returns. The government is under pressure to manage immigration enforcement while addressing the needs of its undocumented population. In May 2025, Iran launched a large-scale deportation campaign targeting approximately 4 million Afghan nationals residing within the country. Israel Tens of thousands of migrants, mostly from Sudan and Eritrea, had crossed the Israeli border between 2009 and 2012. Prime Minister Benjamin Netanyahu said that, "This phenomenon is very grave and threatens the social fabric of society, our national security and our national identity." In May 2012, Israel introduced a law which would allow illegal immigrants to be detained for up to three years, a measure that the Interior Ministry intended to stem the flow of Africans entering Israel across the desert border with Egypt. Israel faces substantial (estimated at 40,000 in 2009) illegal immigration of Arab workers from the Palestinian Authority territories, a migration that includes both workers seeking employment, and homosexuals escaping the social opprobrium of Arab society. Thousands of foreign workers who entered the country on temporary visas have overstayed and live illegally in Israel. There is a debate within Israel as to whether the Israel-born children of foreign workers should be allowed to remain in the country. Libya Before the Libyan civil war, Libya was home to a large population of illegal immigrants from Sub-Saharan Africa, numbering as much as 2,000,000. The mass expulsion plan to summarily deport all illegally residing foreigners was announced by then-current Libyan leader Colonel Muammar al-Gaddafi in January 2008, "No resident without a legal visa will be excluded." Saudi Arabia In 2004, Saudi Arabia began construction of a Saudi–Yemen barrier between its territory and Yemen to prevent the unauthorized movement of people and goods into and out of the Kingdom. Anthony H. Cordesman labeled it a "separation barrier". In February 2004, The Guardian reported that Yemeni opposition newspapers likened the barrier to the Israeli West Bank barrier, while The Independent wrote, "Saudi Arabia, one of the most vocal critics in the Arab world of Israel's 'security fence' in the West Bank, is quietly emulating the Israeli example by erecting a barrier along its porous border with Yemen." Saudi officials rejected the comparison saying it was built to prevent infiltration and smuggling. with nearly 100,000 fleeing to Syria and Jordan each month. Most ventured to Jordan and Syria, creating demographic shifts that have worried both governments. Refugees are mired in poverty as they are generally barred from working in their host countries. Syrian authorities worried that the new influx of refugees would limit the country's resources. Sources such as oil, heat, water and electricity were said to be becoming scarcer as demand were rising. On 1 October 2007, news agencies reported that Syria reimposed restrictions on Iraqi refugees, as stated by a spokesperson for the United Nations High Commissioner for Refugees. Under Syria's new rules, only Iraqi merchants, businessmen and university professors with visas acquired from Syrian embassies may enter Syria. ==See also==
