New York Harbor Due to its history the United States can be described as an
immigration country. American immigration history can be viewed in four epochs: the colonial period, the mid-19th century, the start of the 20th century, and post-1965. Each period brought distinct national groups, races, and ethnicities to the United States.
Colonial period During the 17th century, more than 170,000
English people migrated to the modern United States. From 1700 to 1775, between 350,000 and 500,000 Europeans immigrated: estimates vary in sources. Regarding English settlers of the 18th century, one source says 52,000 English migrated during the period of 1701 to 1775, although this figure is likely too low. 400,000–450,000 of the 18th-century migrants were Scots,
Scots-Irish from Ulster,
Germans,
Swiss, and
French Huguenots. Over half of all European immigrants to Colonial America during the 17th and 18th centuries arrived as
indentured servants. From 1770 to 1775 (the latter year being when the
American Revolutionary War began), 7,000 English, 15,000 Scots, 13,200 Scots-Irish, 5,200 Germans, and 3,900
Irish Catholics migrated to the
Thirteen Colonies. According to Butler (2000), up to half of English migrants in the 18th century may have been young, single men who were well-skilled, trained artisans, like the Huguenots. Based on scholarly analysis,
English was the largest single ancestry in all U.S. states at the time of the first census in 1790, ranging from a high of 82% in Massachusetts to a low of 35.3% in Pennsylvania, where Germans accounted for 33.3%.
Origins of immigrant stock in 1790 The
Census Bureau published preliminary estimates of the origins of the colonial American population by scholarly classification of the names of all
White heads of families recorded in the
1790 census in a 1909 report entitled
A Century of Population Growth. Historians estimate that fewer than one million immigrants moved to the United States from Europe between 1600 and 1799. These statistics do not include the 17.8% of the population who were enslaved, according to the
1790 census.
Early United States era in 1902 The
Naturalization Act of 1790 limited naturalization to "free white persons"; it was expanded to include black people in the 1860s and Asian people in the 1950s. The 1794
Jay Treaty provided freedom of movement for Americans, British subjects, and Native Americans into British and American jurisdictions,
Hudson's Bay Company land excepted. The treaty is still in effect to the degree that it allows Native Americans born in Canada (subject to a
blood quantum test) to enter the United States freely. In the early years of the United States, immigration (not counting the
enslaved, who were treated as merchandise rather than people) was fewer than 8,000 people a year, The
Emergency Quota Act was enacted in 1921, limiting immigration from the
Eastern Hemisphere by national quotas equal to 3 percent of the number of foreign-born from each nation in the
1910 census. The Act aimed to further restrict immigrants from Southern and Eastern Europe, particularly Italian, Slavic, and Jewish people, who had begun to enter the country in large numbers beginning in the 1890s.
Origins of immigrant stock in 1920 The
National Origins Formula was a unique computation which attempted to measure the total contributions of "blood" from each national origin as a share of the total stock of
White Americans in 1920, counting immigrants, children of immigrants, and the grandchildren of immigrants (and later generations), in addition to estimating the
colonial stock descended from the population who had immigrated in the colonial period and were enumerated in the 1790 census.
European Americans remained predominant, although there were shifts toward
Southern,
Central, and Eastern Europe from immigration in the period 1790 to 1920. The formula determined that ancestry derived from Great Britain accounted for over 40% of the American gene pool, followed by German ancestry at 16%, then Irish ancestry at 11%. The restrictive immigration quota system established by the
Immigration Act of 1924, revised and re-affirmed by the
Immigration and Nationality Act of 1952, sought to preserve this demographic makeup of America by allotting quotas in proportion to how much blood each national origin had contributed to the total stock of the population in 1920, as presented below: immigrants working on a farm in 1909; the
welfare system was practically non-existent before the 1930s and the economic pressures on the poor were giving rise to child labor.|alt=Several Polish immigrant workers, some of which are children, are seen standing in their fields after picking berries. Immigration patterns of the 1930s were affected by the
Great Depression. In the final prosperous year, 1929, there were 279,678 immigrants recorded, The slopes of the tops of the differently-colored columns show the rate of percent increase in foreign-born people living in the respective countries. The
Immigration and Nationality Act of 1965, also known as the Hart–Celler Act, abolished the system of national-origin quotas. By equalizing immigration policies, the act resulted in new immigration from non-European nations, which changed
the ethnic demographics of the United States. In the 1980s, this accelerated as the
Federal government of the United States encouraged the immigration of engineers, mathematicians, and scientists from Asia, particularly India and China, to help support
STEM-related endeavors in the country. Skilled immigration from these countries was strengthened through the
Immigration Act of 1990. The
National Academy of Sciences has supported U.S. policymakers to design legislation that attracts foreign mathematicians, engineers and scientists to emigrate to the United States. In 1986 president Ronald Reagan signed immigration reform that gave amnesty to 3 million undocumented immigrants in the country. Appointed by President
Bill Clinton, and over one million persons were
naturalized as U.S. citizens in 2008. The per-country limit nevertheless, China, India, and Mexico were the leading countries of origin for immigrants overall to the United States in 2013, regardless of legal status, according to a
U.S. Census Bureau study. Over 1 million immigrants were granted legal residence in 2011. For those who enter the US illegally across the
Mexico–United States border and elsewhere, migration is difficult, expensive and dangerous. Participants in debates on immigration in the early 21st century called for increasing enforcement of existing laws governing
illegal immigration to the United States, building a
barrier along some or all of the Mexico-U.S. border, or creating a new
guest worker program. Through much of 2006 the country and Congress was engaged in a debate about these proposals. few of these proposals had become law, though a partial border fence had been approved and subsequently canceled. In January 2017, U.S. President
Donald Trump signed an
executive order temporarily suspending entry to the United States by nationals of seven
Muslim-majority countries. It was replaced by another
executive order in March 2017 and by a presidential proclamation in September 2017, with various changes to the list of countries and exemptions. The orders were temporarily suspended by federal courts but later allowed to proceed by the Supreme Court, pending a definite ruling on their legality. Another executive order called for the immediate construction of a
wall across the U.S.–Mexico border, the hiring of 5,000 new border patrol agents and 10,000 new immigration officers, and federal funding penalties for
sanctuary cities. The "zero-tolerance" policy was put in place in 2018, which legally allows children to be separated from adults unlawfully entering the United States. This is justified by labeling all adults that enter unlawfully as criminals, thus subjecting them to criminal prosecution. The Trump Administration also argued that its policy had precedent under the Obama Administration, which had opened family detention centers in response to migrants increasingly using children as a way to get adults into the country. However, the Obama Administration detained families together in administrative, rather than criminal, detention. Other policies focused on what it means for an asylum seeker to claim credible fear. To further decrease the amount of asylum seekers into the United States, Attorney General Jeff Sessions released a decision that restricts those fleeing gang violence and domestic abuse as "private crime", therefore making their claims ineligible for asylum. These new policies that had been put in place were controversial for putting the lives of the asylum seekers at risk, to the point that the ACLU sued Jeff Sessions along with other members of the Trump Administration. The ACLU claimed that the policies put in place by the Trump Administration undermined the fundamental human rights of those immigrating into the United States, specifically women. They also claimed that these policies violated decades of settle asylum law. In April 2020, President Trump said he will sign an
executive order to temporarily suspend immigration to the United States because of the
COVID-19 pandemic in the United States.
Biden administration policies In January 2023, regarding the
Mexico–United States border crisis, Joe Biden announced a new immigration policy that would allow 30,000 migrants per month from Cuba, Haiti, Nicaragua and Venezuela but will also expel the migrants from those countries who violate US laws of immigration. The policy has faced criticism from "immigration reform advocates and lawyers who decry any expansion of Title 42." In fiscal year 2022, over one million immigrants (most of whom entered through
family reunification) were granted
legal residence, up from 707,000 in 2020.
Border Security and Asylum Reform in the Emergency National Security Supplemental Appropriations Act, 2024 The 2024 Emergency National Security Supplemental Appropriations Act represents a change in the immigration system with a focus on strengthening border security and improving asylum processes. This bill, backed by both
Republican senators and endorsed by President
Biden seeks to address the surge in border crossings in the U.S. Mexico border by revolutionizing how migrants and
asylum seekers are processed by border authorities. More specifically, asylum officers to consider certain bars to asylum during screening interviews, which were previously only considered by immigration judges. The legislation aims to streamline provisions for effective management. The proposed law introduces an asylum procedure in the
U.S. Border, where asylum officers from the
U.S. Citizenship and Immigration Services (USCIS) can review asylum applications at a more rapid pace. This new process, called removal proceedings, is detailed in a new section of the
Immigration and Nationality Act (INA) specifically Section 235B. The bill sets a bar for passing an asylum screening by requiring a "reasonable possibility" standard instead of the previous "credible fear" standard. Requiring more evidence at the preliminary screening stages at the same level needed for a full hearing. Notably excluded apprehended individuals between ports of entry from asylum eligibility except under narrow exceptions. This adjustment makes it more difficult for asylum seekers to qualify for a hearing in front of an immigration judge and has raised questions in regards to potential violations against the right to seek asylum and
due process. Furthermore, the legislation establishes an emergency expulsion authority that empowers the branch to expel migrants and asylum seekers during times of " extraordinary migration circumstances." When the seven-day average of encounters between ports of entry exceeds 2,500, the restrictions come into effect. The restrictions continue until the average falls below 1,500 for 14 consecutive days. If this occurs the
DHS Secretary can promptly send migrants back to their home country unless they can prove they face a risk of persecution or torture. The proposed legislation involves around $18.3 billion in funding for the Department of Homeland Security (DHS) to carry out the border policies and changes in the asylum process. Moreover, it designates $2.3 billion to support arrived
refugees through the "Refugee and Entrant Assistance" program. It introduces a program for repatriation enabling asylum seekers to go to their home countries at any point during the proceedings. The proposed legislation also contains clauses that do not affect the humanitarian parole initiatives of the Biden administration, for individuals from Venezuela, Cuba, Haiti and Nicaragua. These individuals are granted approval to travel and a temporary period of parole in the United States.
Origins of the U.S. immigrant population, 1960–2016 Note: "Other Latin America" includes Central America, South America and the Caribbean. ; Refugee numbers with
Afghans being evacuated on a
U.S. Air Force Boeing C-17 plane during the
fall of Kabul in 2021 According to the Department of State, in the 2016 fiscal year 84,988 refugees were accepted into the US from around the world. In the fiscal year of 2017, 53,691 refugees were accepted to the US. There was a significant decrease after Trump took office; it continued in the fiscal year of 2018 when only 22,405 refugees were accepted into the US. This displays a massive drop in acceptance of refugees since the Trump Administration has been in place. On September 26, 2019, the
Trump administration announced that it planned to allow only 18,000 refugees to resettle in the United States in the 2020 fiscal year, its lowest level since the modern program began in 1980. In 2020 the Trump administration announced that it planned to slash refugee admissions to U.S. for 2021 to a record low of 15,000 refugees down from a cap of 18,000 for 2020, making 2021 the fourth consecutive year of declining refugee admissions under the Trump term. The Biden administration pledged to welcome 125,000 refugees in 2024. == Contemporary immigration ==
