Transnational Criminal Investigative Units

HSI’s Transnational Criminal Investigative Units (TCIUs) comprise trained foreign law enforcement officials who work closely alongside HSI to investigate and prosecute individuals involved in transnational criminal activity. These units facilitate information exchange and rapid bilateral investigation of many of the violations of law within HSI’s investigative purview. These violations include: weapons trafficking and counter-proliferation; money laundering and bulk cash smuggling; human smuggling and trafficking; narcotics smuggling; intellectual property rights violations; and other customs-related fraud, child exploitation and cyber-crime. HSI TCIUs span the globe, with locations in 13 countries across North America, Central America, South America, the Caribbean, Europe, Africa and Asia.

TCIUs enhance the host country’s ability to investigate and prosecute individuals involved in transnational criminal activity that threaten the stability and national security of the region and pose continuing threats to the United States. TCIUs identify targets, collect evidence, share intelligence and facilitate the prosecution of transnational criminal organizations through both the U.S. judicial system and in foreign countries.
