 The earliest version of a specialized immigration service was the Immigration and Naturalization Service (INS), created in 1933, in the Department of Labor.Seven years later, in 1940, the INS moved from Labor to its present location in the Department of Justice.Twelve years after moving to DOJ, in 1952, the Immigration and Nationality Act organized all U.S. immigration laws into one statute, and designated "special inquiry officers," the predecessors of immigration judges, to decide questions of deportation.
