Which department supervises Immigration and Customs Enforcement?

The Department of Homeland Security (DHS) is the correct answer because it is the federal department responsible for overseeing Immigration and Customs Enforcement (ICE). Established in response to the September 11 attacks, the DHS integrates multiple agencies and functions to ensure national security, immigration enforcement, and the prevention of terrorism.

ICE is a critical part of the DHS, primarily focusing on enforcement of immigration laws, customs laws, and investigating criminal activities related to both. The alignment under DHS allows for coordinated efforts in maintaining border security while facilitating lawful immigration processes.

The other departments mentioned do not have jurisdiction over ICE. The Department of Justice primarily deals with legal and criminal matters, including the prosecution of federal laws. The Department of Commerce focuses on economic growth, trade, and technology, while the Department of Defense is primarily concerned with military operations and national defense. As such, the Department of Homeland Security is the appropriate supervising entity for Immigration and Customs Enforcement.
