1952 Immigration and Nationality Act, a.k.a. the McCarran-Walter Act (An act to revise the laws relating to immigration, naturalization, and nationality; and for other purposes)
H.R. 13342; Pub.L. 414; 182 Stat. 66.
82nd Congress; June 27, 1952.
Otherwise known as the McCarran-Walter Act, the Immigration and Nationality Act of 1952 was meant to exclude certain immigrants from immigrating to America, post World War II and in the early Cold War. The McCarran-Walter Act moved away from excluding immigrants based simply upon country of origin. Instead it focused upon denying immigrants who were unlawful, immoral, diseased in any way, politically radical etc. and accepting those who were willing and able to assimilate into the US economic, social, and political structures, which restructured how immigration law was handled. Furthermore, the most notable exclusions were anyone even remotely associated with communism which in the early days of the Cold War was seen as a serious threat to US democracy. The main objective of this was to block any spread of communism from outside post WWII countries, as well as deny any enemies of the US during WWII such as Japan and favor “good Asian” countries such as China. The McCarran-Walter Act was a strong reinforcement in immigration selection, which was labeled the best way to preserve national security and national interests. President Truman originally vetoed the law, deeming it discriminatory; however there was enough support in Congress for the law to pass.
