The Immigration Act of 1891, also known as the 1891 Immigration Act, was a modification of the Immigration Act of 1882, focusing on immigration rules and enforcement mechanisms for foreigners arriving from countries other than China. It was the second major federal legislation related to the mechanisms and authority of immigration enforcement, the first being the Immigration Act of 1882 (there were other, more minor pieces of legislation passed in the 1880s). The law was passed on March 3, 1891, at the end of the term of the 51st United States Congress, and signed into law by then United States President Benjamin Harrison
