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.

A Dutch family at Ellis Island between 1915 and 1920.

As host to more immigrants than any other country, the United States has been shaped and reshaped by immigration over the centuries, with the issue at times becoming a flashpoint. This article covers the history of U.S. immigration and the major laws governing immigration, and provides a comprehensive overview of the present-day immigrant population.

Migrants enrolled in the Migrant Protection Protocols are processed by U.S. Customs and Border Protection officers.

The Biden administration's court-ordered restart of the controversial Migrant Protection Protocols, known informally as the Remain in Mexico policy, puts it in the awkward position of reviving a program it is simultaneously still trying to end. The Trump-era program forced tens of thousands of migrants to wait out the duration of their U.S. immigration court hearings in Mexico and was only questionably successful at deterring unauthorized arrivals.

South Africa hosts the most immigrants of any African country. Yet it faces conflicting pressures, including the legacy of apartheid, a steady outflow of well-educated South Africans, and the need to juggle bilateral labor mobility schemes at a time of economic insecurity and high unemployment. This article traces these pressures and how they have developed over time.

The chaotic arrival of thousands of Haitians at the U.S.-Mexico border in September 2021 was the culmination of a journey through the Americas that began for many a decade ago. This article examines how Brazil became a refuge for many after Haiti’s devastating 2010 earthquake, and how Haitians then moved on to Chile and other countries as conditions changed, and then onward again further north.

A U.S. Customs agent looks at wreckage following the 9/11 terror attacks

After the terror attacks of September 11, 2001 the U.S. immigration system was retooled to have a strong national security focus. This restructuring had dramatic effects on government operations and resource allocations, not to mention on the lives of immigrants and the U.S. born alike. Twenty years on from 9/11, this article examines the changes put in place or accelerated as a result of the attacks.

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.
