U.S. Customs and Border Protection (CBP) is the unified border agency within the Department of Homeland Security (DHS). CBP combined the inspectional workforces and broad border authorities of U.S. Customs, U.S. Immigration, Animal and Plant Health Inspection Service and the entire U.S. Border Patrol. CBP includes more than 41,000 employees to manage, control and protect the Nations borders, at and between the official ports of entry.
Individuals seeking entry into the United States are inspected at Ports of Entry (POEs) by CBP officers who determine their admissibility. The inspection process includes all work performed in connection with the entry of aliens and United States citizens into the United States, including preinspection performed by the Immigration Inspectors outside the United States.
