first major law restricting immigration to le (le means the) United States :)) Hope this helps muah! :*****
The Chinese Exclusion Act of 1882 was a law that banned Chinese laborers from migrating to the U.S. and denied them the right to become naturalized citizens. It was motivated by anti-Chinese sentiment and economic concerns, and it marked the first federal immigration law based on racial discrimination. The act was in effect until it was repealed in 1943.
