Cultural Property, Art and Antiquities

Returning a nation's looted cultural heritage or stolen artwork promotes goodwill with foreign governments and citizens while protecting the world's cultural heritage and knowledge of past civilizations. Federal importation laws give HSI the authority to lead investigations involving the illicit importation and distribution of cultural property, art and antiquities. International Operations leads the execution of many of these investigations through specially-trained, internationally-assigned investigators who coordinate with private institutions and foreign governments, in addition to domestic HSI investigators' coordination with federal, state, and local agencies.

Biometric Identification Transnational Migration Alert Program

The Biometric Identification Transnational Migration Alert Program is an International Operations-led program that offers the capability to search, enroll and identify known or suspected terrorists, violent international gang members and other individuals of interest.

Partnership with Interpol Washington, the U.S. National Central Bureau

HSI special agents provide leadership and serve as points of contact at Interpol Washington's U.S. National Central Bureau. This partnership enhances ICE's access to the international law enforcement authorities in the 189 other member countries of Interpol. Interpol Washington is Interpol's national point of contact and provides 24/7/365 secure communications and access to Interpol's services. These services facilitate international police communications in support of U.S. efforts to combat transnational crime and terrorism and to enhance national security. In accordance with a Departments of Justice and Homeland Security memorandum of understanding, the U.S. National Central Bureau directorship rotates between the two departments and reports directly to the deputy attorney general and the deputy secretary. Also, the bureau's deputy director – currently an HSI special agent – succeeds the director for a three-year rotation at the Senior Executive Service level. International Operations currently maintains three positions at Interpol, which include the deputy director of the U.S. National Central Bureau, who will soon be the director, assistant director, and program manager/liaison.
