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.

U.S. immigration officials walk by a courthouse in Seattle.

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.

A woman in Italy is vaccinated before travel in 1951.

Requirements that international travelers and migrants prove vaccination against certain diseases are about as old as vaccines themselves. In some cases, vaccine certificates predated the existence of government-issued passports. This article explores the history of these requirements, which began with smallpox and have since been applied for diseases including cholera, polio, yellow fever, and, recently, COVID-19.

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 border asylum proposed rule the Biden administration unveiled in February represents a bid to save the U.S. asylum system, not shut it down, as some contend. Whether it can succeed, however, depends on how it is implemented and on other steps that are beyond the bounds of the proposed rule, as this commentary explains.

Pandemic-related U.S. policies have led to more than 2.6 million migrant expulsions at the U.S.-Mexico border, expanded public benefits to cover millions more U.S. residents, and offered free COVID-19 vaccines and treatment. Many of these policies are now likely to end as the Biden administration in May 2023 formally declares the pandemic to be over, although what comes next remains unclear.

At his term's midpoint, President Joe Biden has relied on executive action to advance his immigration agenda more than his predecessors, including Donald Trump. Yet many of the changes to interior enforcement, humanitarian protection, and other areas have been overshadowed by the record pace of arrivals at the U.S.-Mexico border, which has presented the administration with major policy and operational challenges.
