National Origins Act

In 1924 Congress passed a discriminatory immigration law that restricted the immigration of Southern and Eastern Europeans and practically excluded Asians and other nonwhites from entry into the United States. This act instituted admission quotas by using the 1890 census to determine the population of a particular nationality group; the government then only allowed 2 percent of that population into the nation. In addition, the act completely barred immigration for all those whom the Supreme Court prohibited from obtaining U.S. citizenship, specifically Asians. The National Origins Act drastically lowered the annual quota of immigration, from 358,000 to 164,000. Congress abolished the national origins quota system in the 1960s.
