Customs and Border Protection (CBP) is the primary federal agency responsible for securing the United States borders and facilitating lawful international trade and travel. Established during the reorganization that created the Department of Homeland Security in 2003, the agency consolidated functions formerly performed by the United States Customs Service and the Immigration and Naturalization Service. CBP operates at ports of entry, along land borders, and in coastal regions, interfacing with a wide array of federal, state, and international partners.

History

CBP emerged from post-9/11 restructuring linked to the Homeland Security Act of 2002 and the creation of the Department of Homeland Security. Predecessor entities include the United States Customs Service, with origins tracing to the Tariff Act of 1789, and the Immigration and Naturalization Service, formed under the Department of Justice. The consolidation aimed to integrate functions represented by agencies such as the U.S. Border Patrol, Office of Field Operations, and Air and Marine Operations. Major historical events shaping CBP policy include responses to the September 11 attacks, implementation of the USA PATRIOT Act, and trade enforcement actions under North American Free Trade Agreement mechanisms and World Trade Organization dispute settlements.

Organization and Structure

CBP is a component of the Department of Homeland Security and is led by senior executives appointed under statutes governing federal agencies. Principal components include the Office of Field Operations, the United States Border Patrol, and Air and Marine Operations. The agency coordinates with entities such as the Federal Emergency Management Agency, the Transportation Security Administration, the Federal Bureau of Investigation, and international partners including Canada Border Services Agency and Servicio de Administración Tributaria. Regional organization aligns with major ports, sectors, and field offices analogous to structures used by U.S. Coast Guard districts and Federal Bureau of Prisons divisions.

Roles and Responsibilities

CBP enforces statutes enacted by Congress, including immigration, trade, and customs laws such as provisions from the Tariff Act of 1930 and requirements under the Immigration and Nationality Act. Its responsibilities encompass processing arriving travelers at international airports like John F. Kennedy International Airport and Los Angeles International Airport, inspecting cargo under programs linked to U.S. Customs and Border Protection's Centers of Excellence and Expertise, and patrolling the United States–Mexico border and the United States–Canada border. CBP also administers programs created through interagency agreements with the Department of Commerce and Department of State and enforces trade remedies akin to actions through the United States Trade Representative.

Operations and Programs

Major CBP operations include passenger inspection at ports of entry, cargo examination, immigration enforcement, trade compliance, and border security activities such as checkpoints and patrols. Programs include the Global Entry trusted traveler program, Automated Commercial Environment for import processing, and trade enforcement collaborations with U.S. Immigration and Customs Enforcement in areas overlapping with Operation Last Frontier-style initiatives. CBP undertakes joint operations with the Drug Enforcement Administration, U.S. Marshals Service, and foreign law enforcement units such as Royal Canadian Mounted Police task forces, and employs targeted initiatives to interdict narcotics, counterfeit goods, and human smuggling networks.

Training, Equipment, and Technology

CBP training is conducted at facilities that align with professional standards similar to academies used by the Federal Law Enforcement Training Centers, and includes programs for Border Patrol agents, officers at ports of entry, and aircrews. Equipment and platforms range from surveillance aircraft comparable to Lockheed P-3 Orion operations, sea vessels resembling assets of the U.S. Coast Guard, tactical vehicles, biometric systems interoperable with databases such as those managed by the Federal Bureau of Investigation and Department of State passport records, and nonintrusive inspection technologies used for cargo screening. CBP leverages information systems and data-sharing partnerships with agencies like the National Aeronautics and Space Administration for situational awareness and the Department of Defense for operational support when authorized.

CBP’s legal authority is grounded in federal statutes enacted by the United States Congress and is subject to oversight by legislative committees including the United States Senate Committee on Homeland Security and Governmental Affairs and the United States House Committee on Homeland Security. Judicial review arises through cases in the United States Court of Appeals and the United States Supreme Court on matters such as search and seizure and administrative law. Inspector oversight mechanisms include the Department of Homeland Security Office of Inspector General and reporting requirements to the Government Accountability Office. Interagency memoranda and international agreements, including protocols with Mexico and Canada, further define operational authorities and responsibilities.

Criticism and Controversies

CBP has faced scrutiny and legal challenges related to civil liberties, use-of-force incidents adjudicated in federal courts, and detention practices that prompted investigations by the Department of Justice and reports by the American Civil Liberties Union. Controversies have arisen over policies at the United States–Mexico border, implementation of immigration directives under various presidential administrations including the Trump administration and the Biden administration, and procurement practices examined by the Government Accountability Office. High-profile incidents and media coverage have spurred congressional hearings before committees such as the House Committee on Oversight and Reform and litigation involving non-governmental organizations and state attorneys general.
