Page Act of 1875 was the first act restricting immigration. The Immigration Act of 1882 imposed a 50 cent head tax to fund immigration officials. The Chinese Exclusion Act (1882) allowed the U.S. to suspend Chinese immigration, a ban that was intended to last 10 years. The Act of 1891 extended the federal government's power to deport immigrants and established a Commissioner of Immigration in the Treasury Department.[1][2] The Supreme Court held that this act was constitutional in Yamataya v. Fisher (Japanese Immigrant Case). The Geary Act of 1892 extended and strengthened the Chinese Exclusion Act.

1900-1945

The Immigration Act of 1903, also called the Anarchist Exclusion Act, added four inadmissible classes: anarchists, beggars, and importers of prostitutes. The Naturalization Act of 1906 standardized naturalization procedures, made some knowledge of English a requirement for citizenship, and established the Bureau of Immigration and Naturalization. The Immigration act of 1907 restricted immigration for certain classes of disabled and diseased people. The Immigration Act of 1917 (Barred Zone Act) restricted immigration from Asia by creating an "Asiatic Barred Zone" and introduced a reading test for all immigrants over fourteen years of age, with certain exceptions for children, wives, and elderly family members. The Immigration Act of 1918 expanded on the provisions of the Anarchist Exclusion Act. The Emergency Quota Act of 1921 restricted annual immigration from a given country to 3% of the number of people from that country living in the U.S. in 1910. The Immigration Act of 1924 (also known as the Johnson Act) introduced nationality quotas, aimed at freezing the current ethnic distribution in response to rising immigration from Southern and Eastern Europe, as well as Asia. The National Origins Formula was established with the Immigration Act of 1924. Total annual immigration was capped at 150,000. Immigrants fit into two categories: those from quota-nations and those from non-quota nations. Immigrant visas from quota-nations were restricted to the same ratio of residents from the country of origin out of 150,000 as the ratio of foreign-born nationals in the United States. The percentage out of 150,000 was the relative number of visas a particular nation received. Non-quota nations, notably those contiguous to the United States only had to prove an immigrant's residence in that country of origin for at least two years prior to emigration to the United States. Laborers from Asiatic nations were excluded but exceptions existed for professionals, clergy, and students to obtain visas. The Nationality Act of 1940 pertains chiefly to "Nationality at Birth," Nationality through Naturalization," and "Loss of Nationality". Certain miscellaneous matters are also dealt with. The Chinese Exclusion Repeal Act of 1943 repealed the Chinese Exclusion Act and permitted Chinese nationals already in the country to become naturalized citizens.

1945-1999

The Immigration and Nationality Act of 1952 (or McCarran-Walter Act) somewhat liberalized immigration from Asia, but increased the power of the government to deport illegal immigrants suspected of Communist sympathies. The Immigration and Nationality Act of 1965 (or Hart-Celler Act) discontinued quotas based on national origin,
