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.

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.

The U.S. immigration enforcement system increasingly depends on other countries to help halt irregular movements through the Americas and accept the return of unauthorized migrants. Foreign governments play a crucial and yet underappreciated role in migration management, and can either aid or frustrate U.S. border-control aims, as this article explores.

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. This article provides an overview of the standoff and the larger context of current and past state-federal tensions over immigration enforcement.

While the Tibetan government-in-exile has become a model for displaced communities, a series of factors have contributed to the shrinking population in South Asia, as this article describes.
