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

A construction crew works on a wall the U.S.-Mexico border.

The number of border walls globally has multiplied at a rapid clip, from fewer than five at the end of World War II to more than six dozen now, with more under construction. Most of the world's border fortifications have been built since the turn of the millennium, and are intended to accomplish a range of functions. This article charts the remarkable growth and normalization of border walls globally.

Artificial intelligence systems that promise speedier travel and improved tools to halt smuggling and detect illegal entry have been embraced by border officials across the globe. But critics contend they also pose serious privacy concerns, which may become more pronounced as technologies evolve. This article examines the challenges and promises.

While Donald Trump’s presidency is perceived as being the most active on immigration, touching nearly every aspect of the U.S. immigration system, President Joe Biden’s administration has far outpaced his predecessor in the number of executive actions taken during his first year in office—even as the pace of change has gone largely unnoticed, as this article explores.

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.

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.

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.
