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.

U.S. Border Patrol agents prepare to transport unauthorized migrants to Mexico under Title 42.

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.

The COVID-19 pandemic both shocked the global mobility system and reaffirmed the centrality and resiliency of human mobility. Four years on, public and political attention to COVID-19’s unprecedented consequences for cross-border movement has waned.
