Are there different types of ICE agent roles?

1. Homeland Security Investigations: the special agents and investigators

Homeland Security Investigations (HSI) is ICE’s principal investigative component and fields special agents who carry federal criminal authorities to probe transnational crime—narcotics, human trafficking, cybercrime, financial crime, human rights violations and more—operating across the U.S. and around the world ^{[1] [4]}. HSI special agents complete inter-agency and HSI-specific training and constitute thousands of personnel deployed to hundreds of domestic and international offices, with career tracks that include criminal analysts, seized‑property specialists and technical enforcement officers ^{[5] [6] [3]}.

2. Enforcement and Removal Operations: deportation, detention and field officers

Enforcement and Removal Operations (ERO) handles the arrest, detention and removal side of ICE’s mission; its officers—sometimes labeled deportation or detention and deportation officers—manage case processing, coordinate with immigration courts and run many of the domestic enforcement actions that members of the public most often encounter ^{[1] [2] [4]}. Training pathways differ by position: law‑enforcement roles undergo multi‑month academies and continuous post‑academy instruction tailored to their duties ^{[6] [4]}.

3. Intelligence, technical enforcement and cyber specialists

ICE houses intelligence officers, technical enforcement officers and cyber specialists who gather and analyze data, conduct digital forensics, manage surveillance technology and partner with other agencies and private vendors to support investigations ^{[7] [8] [9]}. Those functions are distinct from street arrests and include responsibilities such as monitoring transnational criminal organizations, running surveillance programs and supporting HSI cases with technical expertise ^{[1] [7]}.

4. Legal, programmatic and mission‑support staff

Not all ICE employees are sworn law‑enforcement agents: the Office of the Principal Legal Advisor (OPLA) contains attorneys who litigate removal cases and shape legal strategy, while management, human resources, contractors, evidence custodians (seized property specialists) and other mission‑support roles sustain field operations ^{[1] [3]}. ICE’s public materials and hiring guides list careers ranging from cybersecurity and emergency management to aviation and detention support, underscoring the agency’s administrative breadth ^{[5] [3]}.

5. Roles blur in practice and politics—accountability and recruitment debates

Reporting and watchdog accounts document that the lines between roles can blur—agents from varied federal units have been reallocated to immigration enforcement, and controversies over tactics, masks, unmarked vehicles and public raids have raised legal and civil‑rights questions ^{[10] [6]}. Internal dissent and political shifts have also influenced recruitment and standards, with critics arguing that rapid hiring and policy priorities can change the agency’s character, a claim chronicled in investigative reporting and reflected in debates among lawmakers and career agents ^[6].

6. What this means for the public and for oversight

The multiplicity of ICE roles matters for how enforcement is planned, supervised and legally constrained: investigative HSI agents use different authorities and tradecraft than ERO officers who execute removals, and intelligence or technical staff can enable operations without being visible on the street; oversight, training and policy guidance therefore must account for distinct authorities, capabilities and risks across these roles ^{[1] [4] [7]}. Public descriptions from ICE and DHS list these separate directorates and dozens of specialty occupations, but reporting also shows that operational practice and politics can shift who does what and where ^{[5] [1] [6]}.
