ICE Immigration Customs Enforcement Coloring Book
Enforcement and Removal Operations (ERO)
Enforcement and Removal Operations (ERO) enforces U.S. immigration laws at, within, and beyond the nation’s borders. ERO plays a critical role in protecting national security, public safety, and the integrity of the immigration system by focusing enforcement efforts on individuals who pose a threat or who have violated U.S. immigration laws.
ERO prioritizes convicted criminal undocumented aliens, gang members, immigration fugitives, and individuals who illegally re-enter the United States after removal. ERO officers assigned to INTERPOL also assist in Fugitive Arrest and Removal (FAR) cases by identifying and apprehending foreign fugitives wanted for crimes committed abroad who are now at large in the U.S.
ERO manages the full immigration enforcement lifecycle, including identification and arrest, detention, domestic transportation, bond management, supervised release, and alternatives to detention. The directorate also carries out removals to more than 150 countries worldwide.
Homeland Security Investigations (HSI)
Homeland Security Investigations (HSI) is the principal investigative arm of the Department of Homeland Security. HSI is responsible for investigating, disrupting, and dismantling transnational criminal organizations and terrorist networks that exploit U.S. immigration, customs, and trade systems.
HSI employs more than 8,700 personnel—including special agents, criminal analysts, and mission support staff—assigned to over 237 offices across the United States and more than 93 offices internationally. HSI has broad federal authority to investigate the illegal cross-border movement of people, goods, money, technology, and other contraband.
Investigative priorities include terrorism, national security threats, narcotics smuggling, transnational gangs, child exploitation, human trafficking and smuggling, cybercrime, financial fraud, money laundering, export violations, intellectual property theft, trade fraud, identity and benefit fraud, human rights violations, and war crimes.
Working with domestic and international partners, HSI gathers evidence, supports prosecutions, executes search warrants, seizes criminal assets, and takes decisive action to dismantle criminal networks worldwide—protecting national, border, and economic security.
Management and Administration (M&A)
The Management and Administration (M&A) directorate provides the essential infrastructure that enables ICE to carry out its mission effectively. M&A oversees performance management, human capital programs, recruitment, equal employment opportunity initiatives, and long-term organizational planning.
M&A manages ICE’s budget, financial operations, procurement, facilities, property, privacy, and policy programs in compliance with all federal laws and regulations. The directorate also delivers secure, integrated information technology systems and oversees acquisition strategies and contract management.
Additionally, M&A supports agency training requirements, ensures timely responses to Freedom of Information Act (FOIA) requests, and promotes diversity, accountability, and operational efficiency across ICE.
Office of the Chief Financial Officer (OCFO)
The Office of the Chief Financial Officer (OCFO) manages ICE’s financial and physical resources and delivers critical financial services across the agency. OCFO allocates funding to operational components using best practices that align strategic planning, budgeting, and performance outcomes with sound financial decision-making.
Office of the Principal Legal Advisor (OPLA)
The Office of the Principal Legal Advisor (OPLA) is the largest legal program within DHS, employing more than 1,700 attorneys and nearly 300 support staff. OPLA serves as the exclusive legal representative of DHS in immigration removal proceedings before the Executive Office for Immigration Review.
OPLA litigates removal cases involving criminal aliens, terrorists, human rights violators, and other removable individuals. The office also provides comprehensive legal advice to ICE programs on immigration, customs, and criminal law enforcement authorities; ethics; FOIA and Privacy Act compliance; federal tort claims; and administrative law matters.
OPLA represents ICE before federal courts and administrative bodies and provides essential legal support to the Department of Justice in prosecuting ICE cases and defending agency authorities.
Office of Professional Responsibility (OPR)

OPR promotes organizational integrity by conducting independent reviews of ICE operations and impartially investigating allegations of serious misconduct involving employees or contractors.
OPR also manages agency security programs and addresses internal and external threats against ICE personnel, facilities, and operations to ensure accountability, transparency, and public trust.
