The U.S. Immigration Act, also called the "Asiatic Barred Zone Act," increases exclusions.
Date: 1917
The act restricts the immigration of "undesirables" from other countries, including "idiots, feeble-minded persons, epileptics, insane persons, alcoholics, professional beggars, all persons mentally or physically defective, polygamists, and anarchists" (Britannica).
Also barred are all citizens from the "Asiatic barred zone," which is “any country not owned by the U.S. adjacent to the continent of Asia."
The act imposes an English literacy test and an increased tax of eight dollars per person aged 16 or older. This act also adds a classification of "constitutional psychopathic inferiority," in which all people who are classified as such, including many LGBTQ+ people, are banned from entering the U.S.
