The Immigration Act of 1903, also called the Anarchist Exclusion Act, was a law of the United States regulating immigration. It codified previous immigration law, and added four inadmissible classes: anarchists, people with epilepsy, beggars, and importers of prostitutes. It had minimal impact and its provisions related to anarchists were expanded in the Immigration Act of 1918.
