H.R. 5517 — Northern Border Security Enhancement and Review Act

This section revises the northern border threat analysis under the Northern Border Security Review Act to require submission by September 2, 2026, and biennially thereafter. It requires the Secretary of Homeland Security to update the Department’s northern border strategy within 90 days after each analysis or notify the appropriate congressional committees if no update is needed. It also requires the Secretary to provide those committees a classified briefing on the analysis within 30 days after each submission. Within six months of enactment, the section directs the Secretary, through the Executive Assistant Commissioner of Air and Marine Operations at U.S. Customs and Border Protection, to develop performance measures assessing the effectiveness of air and maritime operations at securing the northern border between ports of entry.
