"In the United States, the Emergency Quota Act (ch. 8, 42 Stat. 5, also known as the Johnson Quota Act) of 1921-05-19 was an immigration quota that limited the annual number of immigrants who could be admitted from any country to 2% of the number of persons from that country living in the United States in 1910, according to United States Census figures. This totaled about 357,802 immigrants. Of that number just over half was allocated for northern and western Europeans, and the remainder for eastern and southern Europeans, a 75% reduction from prior years. Professionals were allowed in despite their origins. The act was passed in a time of swelling isolationism following World War I."

"The Immigration Act of 1924, which included the National Origins Act, Asian Exclusion Act or the Johnson-Reed Act, was a United States federal law that limited the number of immigrants who could be admitted from any country to 2% of the number of people from that country who were already living in the United States in 1890, according to the Census of 1890. It excluded immigration to the US of Asians. It superseded the 1921 Emergency Quota Act. The law was aimed at further restricting the Southern and Eastern Europeans who had begun to enter the country in large numbers beginning in the 1890s, as well as East Asians and Asian Indians, who were prohibited from immigrating entirely. It set no limits on immigration from Latin America."
