how the Black Codes (Jim Crow Laws) and the restrictive immigration laws of the 1900s were similar. don't get how they are alike

Answer 1

Both kinds of laws placed restrictions on people based on whom they were/are. Factors include race, national origin, and other factors inherent in the person or persons. In essence, both say to people, "We don't like you, so you don't have the same rights as we do."
