Northern Border Security Enhancement and Review Act

This bill amends the Northern Border Security Review Act to establish a new annual deadline for threat analysis (September 2, 2025, and each year after) and requires the Department of Homeland Security to update its northern border strategy within 90 days of each analysis. It mandates that the Secretary provide a classified briefing to congressional committees within 30 days of each threat analysis and develop performance measures for U.S. Customs and Border Protection's Air and Marine Operations to secure the northern border in air and maritime areas within six months of enactment. The bill directly affects the Department of Homeland Security and congressional committees by imposing specific reporting deadlines and review requirements. These changes focus on improving the frequency and structure of security assessments without altering existing border security operations.
