Immigration, Citizenship, and Eugenics in the U.S.

For years all immigrants were allowed into the U.S., but some could not become citizens. Later, certain nationalities were limited or completely banned from entering the U.S. This episode outlines those changes through the 1980s and discusses the pseudoscience of eugenics and how it was used to justify such bigotry and even involuntary sterilizations in the 20th Century.
