- Gentlemen’s Agreement (1907): An informal agreement between the US and Japan that restricted Japanese immigration in exchange for desegregation of public schools in San Francisco.
- Immigration Act of 1917: Imposed literacy tests, banned immigrants with disabilities, and excluded immigrants from certain “barred zones” (primarily Asian countries).
- Immigration Act of 1924: Significantly reduced immigration from countries outside the Western Hemisphere, banning immigration from Asia and capping the total annual quota at 165,000.
