What ethic group did the immigration laws of the 1800's and early 900's discriminate against ?

During the 1800s and early 1900s various ethnic groups were restricted from immigrating. Mainly asian (and specifically chinese) people were discriminated against. The Exclusion Act of 1882 is considered by many historians to be the first explicit exclusionary immigration restriction made to one particular nationality in its entirety. Immigration of chinese laborers was prohibited right then. This was largely the result of racial prejudice from the American people and their authorities.

Hope this helps!
