The
Immigration and Nationality Act of 1952 , also known as the
McCarran–Walter Act, restricted immigration into the U.S. and is codified under
Title 8 of the United States Code . The Act governs primarily immigration to and citizenship in the United States. It has been in effect since December 24, 1952. Before this Act, a variety of statutes governed
immigration law but were not organized within one body of text.
