The correct answer is B) The United States established a quota system to limit immigration.
The statement that describes immigration to the United States in 1920 is "The United States established a quota system to limit immigration."
Immigration was such an important issue that worried most Americans in the 1920s. The government had to act. That is why the Johnson-Reed Act of 1924 imposed a quota for immigration. The also known Immigration Act of 1924 limited immigration by establishing a quota through national origins. The act based its numbers regarding the census of 1890 to establish a percentage of immigrants by nationality, although the act completely excluded people from Asia.
