Law went into effect, Mar 3, 1903
The Immigration Act of 1903, also known as the Anarchist Exclusion Act, was a U.S. law that expanded immigration restrictions by barring anarchists, people with epilepsy, beggars, and importers of prostitutes from entering the country. Enforcement was limited—only a few anarchists were deported or denied entry—but the law established a precedent for targeting immigrants based on ideology. British anarchist John Turner was the first person deported under the law, with the Supreme Court upholding the constitutionality of his removal.
