Overview and History
The federal government of the United States has broad authority to regulate immigration matters in the United States and exercises plenary power in the area. However, depending on the area of immigration law you are interested in, you may need to consult publications from a number of different federal departments and agencies to find relevant authority.
Prior to 2002, immigration was primarily governed by Immigration & Naturalization Services (INS). Following the September 11th terrorist attacks, many immigration services were transfered to the newly-created Department of Homeland Security (DHS), effective March 1, 2003.
