The first federal government agency to oversee immigration in the United States მწვანე ბარათი was created by Congress in 1891. Immigration oversight originally belonged to the Office of Immigration in the Treasury Department. As the number of immigrants migrating to the United States increased, so did the tasks of this department. Thus, by 1906, legislatures revised the process for citizenship and set-up the Bureau of Immigration to supervise the naturalization of immigrants in the United States.

The next reformation would not take place until the era of the Great Depression, specifically, in 1933. The tasks that belonged to the Bureau were condensed and assigned to the newly formed Immigration and Naturalization Service (“INS”) agency. INS then became responsible for federal oversight of naturalization and immigration throughout the country.
