Here are some additional key legislation and laws involving immigration to the U.S.:

1790: Naturalization rule. Immigrants are required by the government to live in the U.S. for two years before becoming citizens.

1882: Chinese Exclusion Act. Chinese immigration is banned.

1891: Office of Immigration created. A new government office is created to oversee immigration and naturalization. 

1907: Gentlemen's Agreement. An informal agreement between the U.S. and Japanese governments is made to limit immigration from Japan to the U.S.

1917: Literacy Test. Immigrants are required to pass a literacy test in their native language. Virtually all immigration from Asia is banned.

1924, 1927, 1929: National Origins Acts. The U.S. Border Patrol is formed. A quota admissions system is created limiting immigration by national origin, the number being 2% of the group’s population in the 1820 census. Later versions update the census used to the 1920 census.

1952: McCarran-Walter Act. Race as a reason for exclusion is removed from immigration criteria, but ideology is made a fact in immigration – a person can now be denied entry to the U.S. if they are a communist or a Nazi.
 
1965: Immigration Act Amendments. Quotas by nationality are discontinued, but limits are made to control immigration by the total national number.
