Department of Homeland Security: Border Security Status Report: Third Quarter, Fiscal Year 2017 (Fiscal Year 2017 Report to Congress) [open pdf - 832KB]
"DHS secures our Nation's air, land, and sea borders to prevent illegal activity while facilitating lawful travel and trade. The Department's border security and management efforts focus on three interrelated goals: effectively securing U.S. air, land, and sea borders; safeguarding and streamlining lawful trade and travel; and disrupting and, in coordination with other federal agencies, dismantling transnational criminal and terrorist organizations. DHS has deployed significant levels of personnel, technology, and infrastructure to secure U.S. borders. The integration of intelligence and enforcement capabilities through intergovernmental task forces and partnerships has facilitated better information sharing, leading to the increased interdiction of drugs, weapons, and currency. By focusing on the highest threats and rapidly responding, DHS has strengthened security across the U.S. borders while facilitating international travel and trade."
