The United States entered a new era with the end of the pandemic-era Title 42 expulsions policy. The government’s hopes of maintaining order at the U.S.-Mexico border post-Title 42 may be complicated by factors including authorities’ limited capacity, ongoing litigation, and cooperation from other countries. This article reviews the Biden administration's changing border policies and possible challenges ahead.
Algeria and Morocco sit along a crucial migration corridor between Africa and Europe and have often been defined by their rivalry. Although both have been reluctant to welcome large numbers of sub-Saharan African migrants, their motivations have been different. And historically, their approaches to emigration have been a study in contrasts. This article explores the factors driving migration policy in these two countries.
Central Americans comprise less than one-tenth of the overall U.S. foreign-born population, but their numbers have grown tenfold since 1980, amid economic challenges, political crises, and natural disasters in their region. This article provides a comprehensive look at this population.
Palestinians constitute the world’s longest protracted refugee situation and largest stateless community. Yet their plight has often been eclipsed by more recent displacement crises and dismissed as unsolvable. Other factors have contributed to Palestinian refugees’ situation, including the near impossibility of obtaining citizenship in many host countries and precarious funding for support, as this article explains.
The revised U.S.-Canada Safe Third Country Agreement closes what critics call a loophole that incentivizes unauthorized border crossings of asylum seekers. While responding to Canadian concerns of increasing irregular arrivals from the United States, the change—taken in tandem with U.S. moves at the U.S.-Mexico border—suggests that the Biden administration increasingly wants to rely on neighboring countries to respond to rising asylum claims.
Political and economic crises, new free-movement arrangements, and other trends are transforming countries across Latin America and the Caribbean, a region once known primarily for its emigration. The number of immigrants living in the region has nearly doubled since 2010, an incredible change in a short period of time. This article makes sense of a profound transition underway in the Western Hemisphere.

Historically, nearly one in ten male soccer players at the FIFA World Cup were born in a country other than the one listed on their jersey. At times, the presence of these internationally born athletes can prompt difficult questions about the meaning of the nation and who gets to represent it. This article examines the long history of multinational athletes in top-level competitions.
Migrant millionaires are once again on the move, though headed to new destinations amid fallout from the COVID-19 pandemic and Russia's invasion of Ukraine. While wealthy new arrivals can help provide a healthy tax base and invest in local economies, they can upset housing markets and exacerbate wealth disparities, as this article describes.

The Biden administration’s policy to expel some Venezuelan border arrivals to Mexico marks a significant reversal. For the first time, the U.S. government is invoking the controversial Title 42 expulsions policy not on public-health grounds but as an explicit immigration enforcement measure. The expulsions are being paired with a new humanitarian parole program for up to 24,000 Venezuelans. This article assesses the policy and the uneven treatment of humanitarian migrants by nationality.
Spain has an unconventional immigration system. The national government is primarily responsible for border control, granting legal status to migrants, and other issues, but integration is mostly handled by regional and local governments, allowing for some pioneering policies at the subnational level. This article explores what this system has meant for Catalonia and its capital, Barcelona, which have been considered to be a model throughout Europe.

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.

Despite a widespread perception that the Trump administration has drastically slashed legal immigration to the United States, a review of the data shows that temporary and permanent admissions during the period mostly followed previous trends—at least until the COVID-19 pandemic hit. This article examines trends in temporary, permanent, and humanitarian admissions during the administration, and the related policies that could take a more significant bite ahead if left unchanged.
Before entering office, President Donald Trump promised to deport millions of unauthorized immigrants. Yet despite his general successes in creating a more restrictive and punitive immigration system, this goal has eluded his administration. So-called “sanctuary” policies implemented by state and local governments to limit their cooperation with U.S. Immigration and Customs Enforcement have been a key reason why arrests and removals have not reached earlier peaks.
In the United States, Republicans and Democrats are deeply divided on immigration. President Donald Trump and Democratic presidential nominee Joe Biden have offered sharply diverging policy positions, and the outcome of the election is sure to have profound consequences for the U.S. immigration system. Yet this partisan divide is relatively new. Just two decades ago, the parties were much more united on immigrants’ role in the U.S. economy and society.
A looming furlough of 70 percent of staff at U.S. Citizenship and Immigration Services could halt processing for tens of thousands of green cards, citizenship applications, and other immigrant benefits each month it is in effect. Alongside the long list of Trump administration policies slowing immigration to the United States before and during the COVID-19 pandemic, this could contribute to a precipitous—and likely historic—decline in new arrivals to the United States.
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.
