The Immigration and Nationality Act of 1952, otherwise known as the McCarran Walter Act was enacted on June 27th 1952. It upheld the 'national origins quota' that was made by the Immigration Act of 1924. Making a new system of preferences based on skills, this Act also heavily favored Northern and Western European migrants
Democrat Emanuel Celler complained that this law created the sense that Americans thought people from Eastern Europe and Asia as less desirable/inferior to those of European descent. McCarran and Walter, the founders of this law, responded by saying that the US could face communist infiltration through immigration through migration and that unassimilated "aliens" could ruin the American lifestyle
