GENERAL INFORMATION · CBP OPERATIONS

CBP officers and Border Patrol agents work in different places

Both organizations are components of U.S. Customs and Border Protection, but their principal locations and operational roles are not interchangeable.

Office of Field Operations works at ports of entry

CBP says its Office of Field Operations is responsible for border security and immigration, customs, agriculture, and trade functions at official ports of entry. Those locations include international airports, seaports, and land-border crossings. The uniformed personnel who inspect arriving travelers there are CBP officers.

Border Patrol generally works between ports

U.S. Border Patrol is a separate CBP component whose primary mission is securing the border between official ports of entry. Border Patrol agents patrol land borders and coastal areas and respond to crossings and other activity outside designated inspection facilities.

“CBP” is the parent agency

News releases and statistical pages sometimes use the broad agency name “CBP.” Readers should check whether the underlying activity involved Office of Field Operations at a port, Border Patrol between ports, or another CBP component. Combining those activities can create a misleading picture of airport, land-port, or border enforcement.

ICE is a different DHS agency

Immigration and Customs Enforcement is not part of CBP. ICE Enforcement and Removal Operations conducts interior immigration enforcement and detention functions. An inspection by a CBP officer at an airport or land port is therefore not automatically an ICE arrest, and a Border Patrol encounter is not an ICE administrative arrest.

Why the distinction matters in statistics

CBP encounters, Office of Field Operations inadmissibility determinations, Border Patrol apprehensions, ICE administrative arrests, detention bookings, and removals measure different events. A dated photograph or isolated operation release cannot establish a comparable city ranking or a live nationwide trend.
