主要的反移民政策：
- 1790 年《歸化法》： 僅限白人移民獲得公民身份，實際上將非白人排除在外。
- 排華法案》（1882 年）： 禁止中國勞工進入美國，為期10年，是對移民的重大限製。
- 君子協定》（1907 年）： 美國和日本之間的一項非正式協議，限製日本人移民，以換取舊金山公立學校取消種族隔離。
- 1917 年移民法》： 實行識字測試，禁止殘疾移民，並排除了來自某些 “禁區”（主要是亞洲國家）的移民。
- 1924 年移民法》： 大幅減少來自西半球以外國家的移民，禁止來自亞洲的移民，並將每年的配額總數限製在 165 000 人。
Key Anti-Immigration Policies:
- Naturalization Act of 1790: Limited citizenship to white immigrants, effectively excluding non-white individuals.
- Chinese Exclusion Act (1882): Banned Chinese laborers from entering the United States for 10 years, a significant restriction on immigration.
- 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.
