The Department of Homeland Security’s U.S. Customs and Border Protection (CBP) is the single border agency of the United States.
CBP is the unified border agency within the Department of Homeland Security charged with the management, control, and protection of our Nation’s borders and in between the ports of entry. Our primary mission is to prevent terrorists and terrorist weapons from entering the United States while facilitating legitimate trade and travel.
In this context, CBP Attaches are critical to the success of CBP’s layered security strategy to extend the borders beyond our physical boundaries. We serve as advocates for initiatives promoted by the Department of Homeland Security as well as several others international programs created by CBP such as the Container Security Initiative (CSI), Immigration Advisory Program (IAP), Carrier Initiative Program (CIP), Electronic System for Travel Authorization (ESTA), Customs Trade Partnership against Terrorism (C-TPAT), and Proliferation Security Initiative (PSI) among others.
CBP Attaches coordinate and integrate programs that screen cargo, conveyances, and people who seek entry into our ports before they depart foreign. Attaches also serve as a liaison to the host country’s government, providing technical assistance, fostering secure trade practices, and strengthening border authority principles. We stand eager to work with counterpart administrations throughout the world to enhance their capacity to grapple the complexities of border management in today’s environment.
