Which organization collaborates with HSI in combating transnational crime?

The Office of International Operations plays a crucial role in supporting Homeland Security Investigations (HSI) in their efforts to combat transnational crime. This office is responsible for coordinating U.S. government initiatives and collaborates with various foreign law enforcement agencies. By facilitating information sharing and joint operations, the Office of International Operations enhances HSI's ability to tackle complex transnational criminal activities, such as human trafficking, drug smuggling, and immigration fraud.

The effective collaboration with the Office of International Operations allows HSI to extend its reach beyond domestic borders, leveraging international partnerships to disrupt criminal networks that operate globally. Hence, this collaboration is vital for addressing crimes that cross national boundaries, which is a hallmark of transnational crime.

Other organizations, while important in their respective domains, do not specifically focus on collaboration with HSI for combating transnational crime in the same integrated manner as the Office of International Operations.
