CBP is charged with the dual mission of securing the Nation's borders while facilitating legitimate trade and travel. We accomplish this mission through CBP's six operational offices: the Office of Border Patrol, the Office of Field Operations, the Office of Air and Marine, the Office of International Affairs, the Office of Internal Affairs, and the Office of International Trade. These six offices receive critical support from CBP's other mission-focused offices. Since the publication of our first strategic plan in 2005, CBP has made steady progress toward protecting our country from the threats of global terrorism, illegal migration, and trafficking of narcotics and other contraband; protecting the U.S. economy by enforcing trade laws, intellectual property rights, and collection of revenue on goods imported into the United States; protecting our food supply and agricultural industry from pests and disease; and increasing the security of our airspace.
