What type of cases does the Homeland Security Investigations (HSI) division focus on?

The Homeland Security Investigations (HSI) division primarily focuses on criminal investigations that pertain to immigration, customs, and border security. This includes a wide range of activities such as investigating drug trafficking, human smuggling, and immigration fraud. HSI plays a crucial role in enforcing laws designed to protect national security and public safety, as these functions are integral to maintaining the integrity of the country's borders and immigration systems.

By targeting criminal activities that undermine these areas, HSI not only addresses immediate threats but also supports broader efforts to counter human trafficking and other serious crimes. The investigations conducted by HSI often involve collaboration with other federal, state, and local agencies, as well as international partners, to effectively manage and respond to the complexities surrounding immigration and customs enforcement.

This focus on immigration, customs, and border security sets HSI apart from other agencies that may deal with different issues such as financial audits, environmental regulations, or civil rights violations, which fall outside the direct scope of HSI's mission.
