The Asian Exclusion Act of 1924, also known as the Immigration Act of 1924 or the Johnson-Reed Act, was a law passed by the United States Congress that restricted immigration from Asian countries. The act banned immigration from Japan and most other Asian countries by setting quotas based on the number of people of those nationalities already living in the United States. The act also established a national origins quota system, which limited the total number of immigrants who could enter the United States each year and favored immigrants from northern and western European countries. The Asian Exclusion Act was repealed in 1952, when immigration policy was revised to allow more Asians to enter the United States.
