In an era when countries are increasingly exposed to the opportunities and risks associated with the rising global movement of people, policymakers are rethinking approaches to border controls and border management. These policies and programs run the gamut—from facilitating legitimate mobility of people and trade to thwarting unauthorized movements, the latter a significant preoccupation in the post-9/11 era and as publics have become ever less accepting of unauthorized immigration. The research offered here examines the management of borders, enforcement policies and initiatives, and border security technologies.

For Overwhelmed Immigration Court System, New ICE Guidelines Could Lead to Dismissal of Many Low-Priority Cases

New Biden administration guidelines encourage immigration prosecutors to support dismissing many low-priority deportation cases and focus on criminals, threats to national security, and other priorities. This move could have a major impact on clearing backlogs in the overstretched U.S. immigration court system, resulting in quicker determinations in removal and asylum cases, where wait times can presently stretch for years.

Vaccine Requirements Predate the COVID-19 Pandemic by More than a Century

Requirements that international travelers and migrants prove vaccination against certain diseases are about as old as vaccines themselves.

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.
