In the late 1800s, the U.S. government implemented restrictions on Immigration primarily through the Chinese Exclusion Act of 1882. This legislation specifically targeted Chinese laborers, prohibiting their immigration and naturalization, reflecting growing anti-immigrant sentiment and economic concerns. Subsequent laws, such as the Immigration Act of 1891, further tightened regulations and established a federal immigration bureaucracy. These measures marked the beginning of a more restrictive immigration policy in the United States.
