Mission Statement

Homeland Security Investigations’ (HSI) mission is to investigate, disrupt and dismantle terrorist, transnational and other criminal organizations that threaten or seek to exploit the customs and immigration laws of the United States.


Who We Are

HSI is the principal investigative arm of the U.S. Department of Homeland Security, responsible for investigating transnational crime and threats, specifically those criminal organizations that exploit the global infrastructure through which international trade, travel, and finance move. HSI investigates, disrupts, and dismantles terrorist, transnational, and other criminal organizations that threaten or seek to exploit the customs and immigration laws of the United States.

Our Workforce

HSI’s workforce consists of more than 10,400 employees, including special agents, criminal analysts, mission support personnel, and contract staff assigned to offices throughout the United States and around the world.

HSI has more than 7,100 special agents assigned to one of HSI’s Special Agent in Charge (SAC) offices or multiple sub-offices located in 225 cities across the nation. HSI’s domestic footprint is supplemented by more than 2,800 task force officers representing key strategic federal, state and local partners in the fight to combat transnational criminal organizations.

HSI’s international force is DHS’s largest investigative presence abroad, anchored by special agents assigned to U.S. embassies, consulates and Department of Defense (DOD) combatant commands around the globe. HSI has one of the largest international footprints in U.S. law enforcement.


HSI International Operations

HSI International Operations Division develops and supports investigations, initiatives, and operations conducted or supported by HSI Attaché Offices and builds relationships with foreign law enforcement partners to support domestic cases, combat transnational criminal organizations, and prevent terrorist activities.

International Operations protects the nation’s borders by conducting international law enforcement operations and partnering with foreign and domestic counterparts to detect, deter, and dismantle transnational criminal organizations and prevent terrorist activity. International Operations maintains a network of offices and liaisons around the world who conduct investigations against terrorist and other criminal organizations that threaten our national security.

  • HSI Regional Attaché Singapore

The HSI Regional Attaché Office in Singapore has an area of responsibility encompassing not only the country of Singapore, but also Brunei, Indonesia, Malaysia, and Timor-Leste. In addition to the office located at the U.S. Embassy in Singapore, there are also sub-offices at the U.S. Embassy in Jakarta, Indonesia, as well as the U.S. Embassy in Kuala Lumpur, Malaysia.

HSI Singapore is responsible for conducting and supporting HSI investigations and critical programs, as well as coordinating with foreign law enforcement, customs and immigration counterparts.  HSI Singapore supports other ICE, DHS, and USG components and initiatives, as well as develops criminal intelligence related to cross-border criminal activity.  The office coordinates and participates in training programs throughout its AOR, focusing on topics such as financial fraud, human trafficking and smuggling, counter-proliferation, intellectual property rights, and child exploitation to name a few.

HSI Investigative Divisions

  • Investigative Programs

HSI’s Investigative Programs Division furthers HSI’s mission by supporting investigations and operations related to transnational crime, financial and narcotics violations, human trafficking and smuggling, public safety, and labor exploitation. It also supports law enforcement partners through training, technical assistance, and forensic laboratory analysts.

Programmatic areas include contraband smuggling, illicit finance and proceeds of crime, identity and benefit fraud, human smuggling/trafficking, transnational gangs, trade-based money laundering, and labor exploitation.

  • National Security Investigations

The National Security Investigations Division (NSID) plays a critical role in accomplishing ICE’s mission to identify, disrupt and dismantle transnational criminal and terrorist organizations and hostile foreign intelligence entities that threaten the United States and her allies. NSID also leads efforts on investigating and prosecuting human rights violators and war criminals and preventing them from seeking refuge in the United States.

Programmatic areas include counterterrorism and counterintelligence, human rights violators and war crimes, nonimmigrant student/school/employer compliance, school certification, and the Student Exchange and Visitor Information System.

  • Global Trade Investigations

HSI’s Global Trade Investigations (GTI) Division provides oversight and support for investigations of U.S. import and export laws to ensure national security, protect the public’s health and safety, and to stop predatory and illegal trade practices.

The GTI Division oversees HSI’s efforts to combat global intellectual property theft and spearheads HSI’s role in policing the sale and distribution of counterfeit goods on websites, social media and the dark web. HSI’s intellectual property investigations are prioritized to protect the health and safety of U.S. consumers, U.S. economic interests and U.S. government supply chains. The GTI Division also manages HSI’s commercial fraud portfolio, which aims to combat predatory and illegal trade practices that threaten the U.S. economy and national security, and restrict the competitiveness of U.S. industry in world markets. The GTI Division also manages the counter-proliferation investigations program, which focuses on preventing hostile nations and terrorist groups from obtaining U.S. military equipment, dual-use technology, weapons of mass destruction and nuclear materials.

The National Intellectual Property Rights Coordination Center and the Export Enforcement Coordination Center are both led by HSI’s GTI Division and are at the forefront of the federal government’s response to combatting global intellectual property theft and the enforcement of U.S. international trade laws.

Programmatic areas include intellectual property theft and commercial fraud, counter-proliferation (to include weapons trafficking, illegal technology procurement, and sanctions violations), and wildlife trafficking.

  • Operational Technology and Cyber Division

The HSI Operational Technology and Cyber (OTC) Division oversees investigations of internet-related crimes, including cybercrime and child exploitation, and manages initiatives that combine information sharing and technology across DHS.

OTC supports ICE and DHS by improving methods for managing different types of information and operational technology and directing how these tools are shared with other agencies and organizations. OTC, which houses both the HSI Innovation Lab and the Cyber Crimes Center, directly supports HSI’s law enforcement and mission support programs and helps develop major advancements in technology used to combat crime through initiatives such as technical surveillance operations, cybersecurity, computer forensics, Title-III communication intercepts, and the Repository for Analytics in a Virtualized Environment (RAVEn) — HSI’s next-generation platform for data analytics.

OTC proactively uses these technologies to keep pace with emerging computer technology and cyber processes that support investigations into cyber-related criminal activities and vulnerabilities with state-of-the-art investigative methods and computer forensic techniques. OTC also ensures that HSI complies with current information technology standards and security requirements, supports information sharing and intelligence reporting, and gathers and distributes reports based on statistics collected during investigative casework.

Programmatic areas include the Cyber Crimes Center (overseeing computer forensics, cybercrimes, and child exploitation investigations), technical operations, data management and reporting, operational systems development and management, law enforcement information sharing initiative, and the Innovation Lab.
