In the 1880s, Congress proposed the Chinese Exclusion Act, which  stopped Chinese immigration for a period.

Explanation:

The Chinese Exclusion Act was a law issued on May 6, 1882 in response to the massive immigration of Chinese people to the West Coast, mainly San Francisco. It was the first and only official law in US history directed against representatives of a particular nationality (the remaining discriminatory laws enacted in the United States concerned races in general). The law prohibited any Chinese immigration and / or naturalization of Chinese already residing in the United States (however, Chinese-born children in the United States were already considered US citizens). Initially, the law was supposed to extend to 10 years, but it was valid until 1943. By 1917, similar restrictions were extended to immigrants from Asia as a whole.
