What does Homeland Security Investigations (HSI) specialize in?

Homeland Security Investigations (HSI) primarily specializes in investigating and enforcing laws concerning customs, immigration, and a wide range of federal criminal offenses. This includes a focus on crimes such as human trafficking, immigration fraud, and drug smuggling, among others. By handling these areas, HSI plays a critical role in safeguarding national security and upholding the rule of law within the United States.

The scope of HSI's work encompasses various complex and interdisciplinary issues that relate to both customs regulations and immigration matters, highlighting its importance in addressing threats that can emerge from illegal cross-border activities. This specialization aligns with the overarching mission of the Department of Homeland Security, which includes protecting the nation from threats and ensuring the integrity of U.S. immigration systems.

Such a broad focus on customs and immigration-related offenses distinguishes HSI from entities that may enforce labor laws or environmental regulations, as those areas fall under different jurisdictions or governmental agencies that focus on specific regulations and compliance, rather than the comprehensive legal framework within which HSI operates. Similarly, conducting social service programs typically does not align with HSI's objectives, which center on law enforcement and national security.
