Immigration and Customs Enforcement (ICE)

U.S. Immigration and Customs Enforcement (ICE) is the largest investigative agency in the U.S. Department of Homeland Security (DHS). ICE was formed in 2003 pursuant to the Homeland Security Act of 2002, which was passed following the events of September 11, 2001.

ICE has investigative authority over criminal violations of U.S. law relating to illicit trade, travel, immigration and finance as well as violations of employment verification laws and visa violations in the U.S. and abroad. The agency is most notorious for the immigration raids conducted by its Enforcement and Removal Operations unit, which usually result in the wholesale detention and deportation of undocumented workers.
