Effective March 31, 2007, two organizations within the Department of Homeland Security (DHS) have changed their names. The Bureau of Immigration and Customs Enforcement is now called U.S. Immigration and Customs Enforcement (ICE) and the Bureau of Customs and Border Protection is called U.S. Customs and Border Protection (CBP).
DHS was established on January 24, 2003, when 22 federal agencies were reorganized pursuant to the Homeland Security Act of 2002. The Immigration and Naturalization Service (INS) and the U.S. Customs Service were included in that reorganization. On March 1, 2003, the INS was transferred from the Department of Justice, and the Customs Service was transferred from the Department of Treasury, to DHS.
