Northern Border Security Enhancement and Review Act

S. 850, the Northern Border Security Enhancement and Review Act, amends the existing Northern Border Security Review Act. It requires the Department of Homeland Security to update its Northern Border threat analysis periodically (recurring every 3 years, rather than a one-time report) and to add a new element to that analysis: an assessment of recent changes in the number and demographics of apprehensions along the Northern Border, including sector-by-sector trends. It also requires DHS to update its Northern Border strategy within 18 months of enactment and every 5 years after that, incorporating the latest threat analysis, and to brief relevant congressional committees on each threat analysis within 30 days of its submission. Separately, it directs U.S. Customs and Border Protection's Air and Marine Operations to develop performance measures for securing the northern border between official ports of entry, addressing a prior Government Accountability Office recommendation.

The bill primarily affects DHS and CBP, setting new recurring reporting, briefing, and performance-measurement obligations; it does not change border policy or enforcement authority itself. No additional funding is authorized for these requirements.

The Senate passed the bill with amendments by unanimous consent on August 5, 2026. It now goes to the House of Representatives for consideration before it could be sent to the President.
