Pandemic-related U.S. policies have led to more than 2.6 million migrant expulsions at the U.S.-Mexico border, expanded public benefits to cover millions more U.S. residents, and offered free COVID-19 vaccines and treatment. Many of these policies are now likely to end as the Biden administration in May 2023 formally declares the pandemic to be over, although what comes next remains unclear.

Venezuelans comprise one of the fastest-growing immigrant groups in the United States, nearly tripling in size from 2010 to 2021. Much of this migration has been fueled by crisis in Venezuela, where political unrest and economic strife have caused millions to flee since 2015, most remaining in Latin America. Venezuelan immigrants are far more likely than the overall foreign- and U.S.-born populations to have a college degree. Take an in-depth look at this immigrant population.

Severe weather, rising seas, and other consequences of global climate change are affecting the way people live, work, and move around the planet. While there is no clear, direct line between the impacts of climate change and changing human movement, there are indications that the warming planet is indirectly creating or altering patterns of migration. Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.

New Biden administration guidelines encourage immigration prosecutors to support dismissing many low-priority deportation cases and focus on criminals, threats to national security, and other priorities. This move could have a major impact on clearing backlogs in the overstretched U.S. immigration court system, resulting in quicker determinations in removal and asylum cases, where wait times can presently stretch for years.
Most of the world's refugees live in low-income countries where rates of COVID-19 vaccination remain low. Although refugees have been formally included in many governments’ vaccination plans, a combination of factors has made access to jabs difficult, as this article explains.
Immigrants from the Korean peninsula are one of the ten largest foreign-born groups in the United States, but their numbers have actually shrunk in recent years. Immigrants from Korea tend to be older, better educated, and earn higher incomes than the overall immigrant and native-born populations.
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. The COVID-19-era public-health restriction ushered in an unprecedented period of mass expulsions, including of would-be asylum seekers, at the U.S.-Mexico border. Unwinding the policy will be complicated amid predictions of a significant increase in unauthorized migration.

The European Union’s landmark 2016 migration deal with Turkey offered aid and other benefits in exchange for Turkey's assistance in helping reduce arrivals of asylum seekers and other migrants. At its fifth anniversary, the EU-Turkey deal remains one criticized by human-rights advocates and has met frustration from Turkey, but in many ways created a blueprint for other externalization arrangements, as this article outlines.
Across North America and Europe, immigrants rely on public transit at higher rates than the native born. This article explores why migrants are disproportionately more likely to use public transportation, the role these systems play in immigrant integration, and the impact of the COVID-19 pandemic on commuter trips, budgets, and services.
The Rohingya people have been rendered stateless and subjected to repeated abuse that has made them the world’s most persecuted minority, with hundreds of thousands pushed into neighboring Bangladesh, as well as India, Malaysia, Saudi Arabia, and beyond. This article provides a comprehensive overview of the Rohingya, including who they are, where they come from, and how they have been systematically marginalized in their native Myanmar and internationally.
Millions of people flee civil wars for safety elsewhere, but predicting precisely when refugees and asylum seekers will be displaced is not as easy as it seems. There is not always a direct correlation between episodes of violence and patterns of migration. This article explores how civilians require both motivation and opportunity to leave conflict zones.
Climate change has had a devastating impact on many poor Central American farmers, which can contribute to food insecurity and may be prompting migration from the region's Dry Corridor. But the process is not straightforward. As this article explains, most poor farmers rely on a combination of buying, cultivating, and foraging for their food, which makes it difficult to predict how people will react to individual climate events.

Yet over the last three decades Belgium has become a permanent country of settlement for many different types of migrants. Our updated Belgium profile delves into modern migration flows and policies in Belgium which are inching away from a piecemeal approach towards a well-needed, long-term strategy.
Unaccustomed to a large number of migrants, Chile has seen an increase in migrants in the past three decades. Cristián Doña-Reveco and Amanda Levinson examine how the country, still wedded to its dictator-era migration framework, is balancing shifting migration patterns with a piecemeal approach to migration policy.
Jim Cobbe of Florida State University discusses how the close ties between Lesotho (ethnically, almost wholly Basotho) and South Africa (with an even larger Basotho population) are expressed in a history of economic migration, and how new immigrants from China are changing the face of modern-day Lesotho.
Over the past decade, Singapore's multicultural yet nationalist society has experienced substantial inflows of Asian and Western professionals, low-skilled migrants from across Southeast Asia, and new immigrants from nontraditional sending countries.

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.
Two years after the Trump administration’s much-litigated travel ban was created, the policy has demonstrated a significant impact on the admission of foreigners from the banned countries, while also reshaping U.S. security vetting procedures and the refugee resettlement process in enduring ways, as this article explores on the second-year anniversary.
The Trump administration’s latest effort to narrow the ability to apply for asylum at the U.S.-Mexico border hit a legal roadblock within days of implementation, as has been the pattern for much of its immigration agenda. This article examines the actions on asylum, which alongside deployment of active-duty military to the border, are among measures taken to seek to reduce the flow of Central Americans to the United States.
In less than two years as Attorney General, Jeff Sessions oversaw wide-reaching changes to the U.S. immigration system. Even as the zero-tolerance policy, fights with "sanctuary" cities, and DACA termination might be more visible, Sessions' enduring legacy may be his muscular use of a little-noted authority, which he wielded to significantly reshape immigration and asylum policy by referring immigration cases to himself.
