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.

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.

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.

President Joe Biden speaks to journalists at the White House.

During his first 100 days in office, U.S. President Joe Biden took more than three times as many executive actions on immigration as predecessor Donald Trump. While rising encounters at the U.S.-Mexico border have captured major attention, Biden has been remarkably active in areas that have received far less attention, including interior enforcement. This article explores the administration's actions during its first three months.

Los manifestantes marchan en un mitin en Minneapolis pidiendo el fin de ICE

Los llamados de los activistas a "desbancar a la policía", a raíz de una serie de encuentros mortales para los miembros de la comunidad negra, hacen eco de las demandas anteriores de "abolir el ICE" y reflejar una crítica más amplia de los sistemas de aplicación percibidos como demasiado agresivo.

Protesters at a rally in Minneapolis call for abolishing ICE

Calls by activists to "defund the police," in the wake of a string of deadly encounters for Black community members, echo earlier demands to "abolish ICE" and reflect broader criticism of enforcement systems perceived as overly aggressive. Budgets have ballooned at federal immigration agencies and within the immigrant detention system as enforcement has become increasingly muscular in the post-9/11 period.

Digital fingerprint

As governments seek to push their borders out by amassing ever more data on travelers and migrants, their creation of increasingly complex border surveillance systems and use of risk-assessment technologies could ease mobility for some while rendering other groups immobile based on hypothetical risk profiles and decisions that are not publicly known and cannot be challenged, as this article explores.

Growing numbers of African and Asian migrants are moving through Latin America, many hoping to reach the United States or Canada after expensive, arduous, and often dangerous journeys that can take months or even years. As more extracontinental migrants transit through South and Central America, Colombia, Panama, and Costa Rica have developed the most comprehensive policies to manage these flows, sometimes working in coordination with the U.S. government.

Nancy Pelosi and Alexandria Ocasio-Cortez

Ideological differences in the Democratic Party over immigration that were once masked by unity against President Trump’s border wall and immigration agenda are now being exposed as Democratic presidential candidates seek to stand out in a crowded field and amid controversy over an emergency border spending bill. As the 2020 electoral calendar accelerates, how the party navigates the gulf between its most liberal and conservative wings will become a greater challenge for its leaders.

Though a faceoff between the U.S. executive and legislative branches is now in the courts, with President Trump's decision to declare a national emergency so he can allocate more money for construction of a border wall, a less-noted dispute has been taking place over the Department of Homeland Security's decision to add thousands more immigration detention beds than Congress provides annually, as this article explains.

The Trump administration has released a list of hardline immigration demands—including border wall funding, restrictions on federal grants to “sanctuary” cities, and cuts to legal immigration—in exchange for legislation protecting DREAMers. This article examines the prospects for these proposals and more broadly for a legislative fix to resolve the status of unauthorized immigrants brought to the United States as children.

Hundreds of thousands of migrants and asylum seekers reached Europe via the Western Balkans route during the peak of the migration crisis. While Balkan countries initially facilitated movements northward, pressure from the European Union led to cascading border controls, which left thousands stranded in the region. This article examines the role of Balkan countries during the thick of the crisis and subsequent regional impacts.

As Europe begins to move beyond the overwhelming flows of asylum seekers and other migrants it experienced starting in 2015, policymakers are paying significant focus to integration coupled with stepped-up enforcement. 2016 saw a wave of policy innovations facilitating integration as well as returns and deterrence, but it remains to be seen whether Europe will be able to continue and scale up this work in 2017 and beyond, as this Top 10 article explores.

Smugglers and migrants adapted their paths in light of changing conditions in 2016, including the construction of walls and closure of borders. Cuban and Haitian migrants increasingly chose to make their way to the United States through South and Central America rather than by sea. Meanwhile, migrant flows to Europe have splintered into a wider range of routes, seeking new openings through the Western Balkans.

Donald Trump has made a series of postelection statements suggesting he may backtrack on several campaign pledges on immigration, including building a wall across the entire U.S.-Mexico border and deporting all 11 million unauthorized immigrants. Still, his choice of top advisors points to a hard-line agenda. This Policy Beat article examines what some of the better known elements of Trump's immigration policy might look like.

Over the past several decades, in response to the uptick in spontaneous migration flows, there has been a surge in construction of border walls and fences. This trend begs several questions: Why now?

Passed with minimal controversy and public debate, the 2016 spending bill included some of the most substantial immigration policy changes enacted by Congress in the last decade. The changes touched on aspects including temporary worker visas, visa security, and the immigration courts, and could signal a new strategy for legislative change to the immigration system.

The killing of a young woman in San Francisco by an unauthorized immigrant coincided with the Obama administration's rollout of the Priority Enforcement Program, a new vehicle for improving federal-local relations on immigration enforcement. The tragedy has rekindled debate over the role of "sanctuary" cities and propelled illegal immigration to the forefront of the 2016 presidential race.

New migration patterns at the U.S. Southwest border, including a shift in border crossers from primarily Mexican men to Central American families, and from the California and Arizona borders to the Rio Grande Valley, have important implications for U.S. border policy and enforcement strategies, raising questions of what consequences might deter unauthorized Central Americans while still meeting international obligations to protect vulnerable migrants.
