@Blickers,
This is very naïve. Probably the most notorious immigration act was the Chinese Exclusion Act of 1882. It prohibited the immigration of Chinese laborers (wealthy or at least well-off Chinese were not excluded by the act). It was the beginning of a racist period on the west coast which alleged a "Yellow Peril." The Immigration Act of 1924 was aimed at southern Europeans--primarily Catholics--and eastern Europeans, as well as Jews and Asians other than the Chinese. The Immigration Act of 1924 set quotas, and thereafter, quotas were a means of excluding "undesirable" classes of immigrants. The Chinese exclusion act was not repealed until 1947. The first immigration act was in 1790, and required immigrants to prove two years of residence before applying for citizenship. An immigration exclusion act, the Page Act, in 1875 allowed for the appointment of port inspectors, who were to exclude prostitutes and criminals. The criteria for determining who might be considered a prostitute of a criminal were wonderfully vague. An act in 1891 expanded the list of undesirables, to include "idiots, insane persons and paupers." President Roosevelt signed an immigration act in 1903 which excluded anarchists, and allowed port inspectors to question would-be immigrants about their political beliefs. Despite what Emma Lazarus wrote, the the tired, the huddled masses yearning to breathe free were likely to be turned back.
