Which organization primarily oversees the activities of Immigration Customs Enforcement?

The organization that primarily oversees the activities of Immigration and Customs Enforcement (ICE) is the Department of Homeland Security (DHS). DHS was established in response to the events of September 11, 2001, and its primary functions include safeguarding the nation from various threats, including immigration enforcement, which is central to ICE's mission.

ICE operates under DHS and is responsible for the enforcement of immigration laws, investigating customs violations, and combating transnational crime. This alignment with DHS ensures a coordinated approach to national security and immigration policy, reflecting the agency's broader mandate to protect the homeland.

The other organizations listed do not have oversight over ICE. The Department of Justice focuses on federal legal matters and law enforcement issues but does not directly manage ICE. The Federal Trade Commission deals primarily with consumer protection and antitrust issues, and the National Security Agency is focused on national security, particularly in the realm of signal intelligence and cybersecurity. Therefore, these organizations do not play a role in overseeing immigration enforcement activities.
