A top priority for DHS is to keep terrorists and their weapons from entering the U.S. while welcoming all legitimate travelers and commerce. DHS Officers and Agents enforce all applicable U.S. laws, including against illegal immigration, narcotics smuggling, and illegal importation. DHS deploys highly trained law enforcement personnel who apprehend more than 1,000 individuals each day for suspected violations of U.S. laws at and between our ports of entry. Protecting our borders from the illegal movement of weapons, drugs, contraband, and people, while promoting lawful entry and exit, is essential to homeland security, economic prosperity, and national sovereignty. Through increases in Border Patrol staffing; construction of new infrastructure and fencing; use of technology–including sensors, radar, and aerial assets–investments to modernize the ports of entry; and stronger partnerships and information sharing, we are creating a safer, more secure, and more efficient border environment.
