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.

Flags of South American countries.

The South American immigrant population in the United States has grown at a faster rate than that of the overall foreign-born population, amid crises in Venezuela, Colombia, and elsewhere. Yet South Americans still account for only about one in ten U.S. immigrants. While they mirror the overall U.S. immigrant population in several demographic characteristics, there are some notable differences, as this article details.

A member of the Texas National Guard faces migrants in Eagle Pass, Texas.

Rising tensions between Texas and the federal government have sparked fears of a constitutional crisis after the state deployed its National Guard to prevent the U.S. Border Patrol from conducting operations in a city park in Eagle Pass, with Texas Governor Greg Abbott saying the “invasion” of migrants triggered the need for action.

A temple in Dharamsala, India.

The number of Tibetan refugees in India, Nepal, and Bhutan has been on a steady decline since the mid-2000s, posing a threat to the future of an exile community that has developed a robust governance, cultural, educational, and religious structure.

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. Yet if countries are to manage mobility more effectively in future public-health crises, this is an important moment for reflection and learning, as this issue brief explores.
