On February 5, 1917, the
United States Congress passed the
Immigration Act of 1917 (also known as the
Asiatic Barred Zone Act) with an overwhelming majority, overriding President
Woodrow Wilson's December 14, 1916, veto. This act added to the number of undesirables banned from entering the country, including but not limited to “homosexuals”, “idiots”, “feeble-minded persons”, "criminals", “
epileptics”, “insane persons”,
alcoholics, “professional beggars”, all persons “mentally or physically defective”,
polygamists, and
anarchists. Furthermore, it barred all immigrants over the age of sixteen who were
illiterate. The most controversial part of the law was the section that designated an "Asiatic Barred Zone", a region that included much of
Asia and the
Pacific Islands from which people could not immigrate. Previously, only the
Chinese had been excluded from admission to the country. Attempts at introducing
literacy tests were previously vetoed by
Grover Cleveland in 1897 and
William Taft in 1913. Wilson also objected to this clause in the Immigration Act, but it was still passed by Congress on the fourth attempt.
