Northern Border Security Enhancement and Review Act

This bill requires the Department of Homeland Security (DHS) to regularly perform a threat analysis of the northern U.S. border.

The analysis must be performed every three years and include terroristic and criminal threats, recent changes in apprehensions, and improvements needed to prevent terrorism and reduce criminal activity.

Read full summary

DHS must update its northern border strategy not later than September 2, 2026, and every five years thereafter, incorporating the results from the latest threat analysis. DHS must also provide a classified briefing to the appropriate congressional committees.

U.S. Customs and Border Protection’s Air and Marine Operations (AMO) must develop performance metrics to assess the AMO’s effectiveness at securing the northern border between ports of entry in air and maritime environments.
