U.S. Immigration and Customs Enforcement was formed pursuant to the Homeland Security Act of 2002, following the events of September 11, 2001. With the establishment of the Department of Homeland Security, the functions and jurisdictions of several border and revenue enforcement agencies were combined and consolidated into U.S. Immigration and Customs Enforcement. Consequently, ICE is the largest investigative arm of the Department of Homeland Security, and the second largest contributor to the nation's Joint Terrorism Task Force.

The agencies that were either moved entirely or merged in part into ICE included the criminal investigative and intelligence resources of the United States Customs Service, the criminal investigative, detention and deportation resources of the Immigration and Naturalization Service, and the Federal Protective Service. The Federal Protective Service was later transferred from ICE to the National Protection and Programs Directorate effective October 28, 2009. In 2003, Asa Hutchinson moved the Federal Air Marshals Service from the Transportation Security Administration (TSA) to ICE,[12] but Michael Chertoff moved them back to the TSA in 2005.[13]
