Which law prohibited immigration from Asia and favored people from Western or Northern Europe?

• A. Immigration Act of 1907
• B. Emergency Quota Act
• C. Immigration Act of 1924
• D. Naturalization Act of 1790

Answer: (C)

National-origin quotas defined U.S. immigration policy in the 1920s, and the Immigration Act of 1924 is the best example of a law that banned immigration from Asia while favoring Western and Northern Europe. It set strict quotas for each country and used the 1890 census as the baseline, which disproportionately benefited arrivals from Northern and Western European countries and effectively excluded most Asian immigrants. This reflects a deliberate shift toward racially biased immigration limits rather than broad restrictions or citizenship rules alone. The other laws built restrictions or shaped who could become a citizen, but they did not enact the explicit regional preference and severe Asian ban that the 1924 act did.
