Summary
The Immigration Act of 1891 centralized immigration enforcement authority in the federal government, overriding state governments’ previous responsibilities to carry out federal immigration laws. The Act also extended immigration inspections to land borders and created the Office of Superintendent of Immigration to supervise new immigration inspectors at points of entry within the Treasury Department, which was charged with overseeing immigration law in 1882. Beyond strengthening the federal government’s power to enforce immigration law, the 1891 Act also placed further regulations on contract labor and expanded the list of excludable and deportable immigrants to include felons, polygamists, “all idiots, insane persons, paupers or persons likely to become a public charge” as well as those suffering from infectious diseases.
