Final answer:
The annual immigration quota for Filipinos in the 1930s was 50.
Step-by-step explanation:
The annual immigration quota for Filipinos allowed to enter the United States during the 1930s was 50. The quota system was part of the restrictive immigration laws during that period, specifically the Emergency Immigration Act of 1921 and the National Origins Act of 1924. These acts introduced numerical limits and quotas on European immigration, favoring immigrants from Northern and Western Europe over those from Southern and Eastern Europe.
