Border Enforcement

Border Enforcement

Border enforcement is more than its widely perceived role of border guards patrolling external boundaries and inspectors admitting traffic through ports of entry. While those are key components, border enforcement represents a more holistic function, integrating resources and information at and between all ports of entry—whether air, land, or sea—with consular operations abroad and more. The research presented here examines these varied facets.

Controversial U.S. Title 42 Expulsions Policy Is Coming to an End, Bringing New Border Challenges

The United States’ controversial Title 42 migrant expulsions policy will come to an end in May 2022, after more than 1.7 million expulsions over two years. The COVID-19-era public-health restriction ushered in an unprecedented period of mass expulsions, including of would-be asylum seekers, at the U.S.-Mexico border. Unwinding the policy will be complicated amid predictions of a significant increase in unauthorized migration.

Roxham Road Meets a Dead End? U.S.-Canada Safe Third Country Agreement Is Revised

The revised U.S.-Canada Safe Third Country Agreement closes what critics call a loophole that incentivizes unauthorized border crossings of asylum seekers. While responding to Canadian concerns of increasing irregular arrivals from the United States, the change—taken in tandem with U.S. moves at the U.S.-Mexico border—suggests that the Biden administration increasingly wants to rely on neighboring countries to respond to rising asylum claims.
