The Act abolished racial restrictions found in United States immigration and naturalization statutes going back to the
Naturalization Act of 1790. The 1952 Act retained a quota system for nationalities and regions. Eventually, the Act established a preference system that determined which ethnic groups were desirable immigrants and placed great importance on labor qualifications. The Act defined three types of immigrants: immigrants with special skills or who had relatives who were U.S. citizens, who were exempt from quotas and who were to be admitted without restrictions; average immigrants whose numbers were not supposed to exceed 270,000 per year; and refugees. It expanded the definition of the "United States" for nationality purposes, which already included
Puerto Rico and the
Virgin Islands, to add
Guam. Persons born in these territories on or after December 24, 1952, acquire U.S. citizenship at birth on the same terms as persons born in other parts of the United States.
National quotas The McCarran Report of the 1950s supported the quota allocation system of the National Origin Act, asserting that it was the most effective means to "preserve the sociological and cultural balance of the United States". Overall immigration from the "
Asiatic barred zone" was capped at 2,000 people annually. Passage of the act was strongly lobbied for by the
Chinese American Citizens Alliance,
Japanese American Citizens League,
Filipino Federation of America, and
Korean National Association, though only as an incremental measure, as those organizations wished to see national origins quotas abolished altogether. The McCarran–Walter Act allowed for people of Asian descent to immigrate and to become citizens, which had been banned by laws like the
Chinese Exclusion Act of 1882 and
Asian Exclusion Act of 1924. Chinese immigration, in particular, had been allowed for a decade prior to McCarran–Walter by the
Magnuson Act of 1943, which was passed because of America's
World War II alliance with China.
Japanese Americans and
Korean Americans were first allowed to naturalize by the McCarran–Walter Act. Overall changes in the perceptions of Asians were made possible by
Cold War politics; the
Displaced Persons Act of 1948 allowed anticommunist
Chinese American students who feared returning to the
Chinese Civil War to stay in the United States; and these provisions would be expanded by the
Refugee Relief Act of 1953. states:
Quotas by country under successive laws Listed below are historical quotas on immigration from the
Eastern Hemisphere, by country, as applied in given fiscal years ending June 30, calculated according to successive immigration laws and revisions from the
Emergency Quota Act of 1921, to the final quota year of 1965, as computed under the 1952 Act revisions. Whereas the 1924 Act calculated each country's quota by applying the percentage share of each national origin in the 1920 U.S. population in proportion to the number 150,000, the 1952 Act adopted a simplified formula limiting each country to a flat quota of one-sixth of one percent of that nationality's 1920 population count, with a minimum quota of 100. The 1922 and 1925 systems based on dated census records of the foreign-born population were intended as temporary measures; the
National Origins Formula based on the
1920 Census of the total U.S. population took effect on July 1, 1929, with the modifications of McCarran–Walter in effect from 1953 to 1965.
Naturalization A 1962 guideline explained procedures under the Act:
Preference system The 1952 act created four preference categories for quota admissions: 50% for immigrants with essential skills, 30% for parents of adult citizens, 20% for spouses and children of legal residents, and any leftover green cards for siblings and adult children of citizens.
Class of immigrants inadmissible and ineligible for visa Before the Immigration and Nationality Act of 1952, the U.S. Bureau of Immigration vetted newcomers to the United States and often denied entry to new immigrants on subjective conclusion of "perverse" acts such as homosexuality, prostitution, sexual deviance, crime of moral turpitude, economic dependency, or "perverse" bodies like hermaphrodites or individuals with abnormal or small body parts during the period from 1900 to 1924. During this time, immigration authorities denied immigrants entry on this subjective basis by issuing "likely to be a public charge". However, by the 1950s, the immigration authorities solidified this screening measure into law when they enacted a provision against prostitution or any so-called "immoral sexual act". In addition, immigrants deemed feeble-minded, mentally disabled, physically defective, or professional beggars were also ineligible for admission. The Immigration and Nationality Act of 1952 placed provisions on drinking and substance use as a requirement for admission. The act stated that any immigrant who "is or was ... a habitual drunkard" or "narcotic drug addicts or chronic alcoholics" challenged the notion of good moral character, a requirement for citizenship in the United States. As a result, immigrants who participated in excessive alcohol or substance use were inadmissible to the United States.
Abraham Sofaer, Legal Advisor to Secretary of State George Shultz, in consultation with the White House, pushed for amending the law to end the exclusion of people from the US solely on the ground of their political beliefs. Although facing initial congressional backlash, the law was changed in the State Department's 1988 Authorization legislation. As Abraham Sofaer described, ''"The Department of State has long believed that changes are necessary to bring the exclusion and deportation provisions in line with modern reality...It's an anachronism to say that just because someone held some particular political view at some point in his life he should be denied immigration."''
Class of deportable immigrants The Immigration and Nationality Act eliminated numerous due-process safeguards shielding immigrants from deportation abuses. Despite the difficulty of defining "crimes involving moral turpitude", the Immigration and Nationality Act of 1952 established provisions that help define "crimes involving moral turpitude". Under sections, "Inadmissible aliens" and "Deportable aliens", immigrants were ineligible for naturalization if suspected of or committed criminal convictions, illegal gambling, alcohol use, drug trafficking, prostitution, unlawful voting, etc. within five years of entry. The list of crimes involving moral turpitude lead to removal of the immigrant. The Immigration and Nationality Act of 1952 deemed immigrants who were anarchists or members of or affiliated with the Communist Party or any other totalitarian organizations that plan to overthrow the United States as deportable immigrants. Immigrants who were successors of any association of Communism, regardless of name changes, still fell under the deportable immigrants. Immigrants who advocated, taught, wrote, published in support for communism, a totalitarian dictatorship, and the overthrowing of the United States were also deportable immigrants. Under Section 243(h) of the Immigration and Nationality Act of 1952, the Attorney General had the authority to stop the deportation of an immigrant if the Attorney General believed that the immigrant would face physical persecution if he or she returns to the country. The period of withholding deportation was up to the Attorney General as well. ==Enforcement==
