The Immigration Act of 1924, or Johnson–Reed Act, including the National Origins Act, and Asian Exclusion Act (Pub.L. 68–139, 43 Stat. 153, enacted May 26, 1924), was a United States federal law that set quotas on the number of immigrants from certain countries while providing funding and an enforcement mechanism to carry out the longstanding (but hitherto unenforced) ban on other non-white immigrants. The law was primarily aimed at further decreasing immigration of Southern Europeans, especially Italians; and, to a lesser extent, immigrants from countries with Roman Catholic majorities, Eastern Europeans, Arabs, and Jews.[1][2][3][4] The law affirmed the longstanding ban on the immigration of other non-white persons, with the exception of black African immigrants (who had long been exempt from the ban).
