A political crisis marked by Nicaraguan President Daniel Ortega’s growing authoritarianism has sparked the largest emigration in the country’s modern history. Hundreds of thousands have fled, including intellectuals, artists, and academics. They increasingly are heading beyond the traditional destination of Costa Rica, to the United States and beyond, as this article details.

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.
Millions of immigrants fill key sectors in Russia’s economy, help offset its demographic challenges, and support origin communities, particularly in Central Asia. Since Russia's invasion of Ukraine, many have also been pressured into joining the military, and meanwhile face continued marginalization by Russian society. This article outlines the key issues facing these migrants, some of which have been complicated by the fallout from the war.

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.

Poland hosts millions of Ukrainians who fled Russia’s invasion. While the new arrivals have tended to have been greeted warmly, many have questions about the future. As the months pass, many displaced Ukrainians wonder when and if they will return to their native country. This article, based on interviews with dozens of displaced Ukrainians in Poland, examines their experiences.
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.
Mexicans are by far the largest immigrant group in the United States, accounting for nearly one-fourth of all immigrants. However their numbers have been declining and in 2021 there were 1 million fewer than a decade ago. At the same time, despite years in which more new migrants came from China and India, Mexicans once again count as the largest group of new arrivals. This article outlines the changing shape and composition of this immigrant population.
Russia's invasion of Ukraine in 2022 ushered in renewed scrutiny of citizenship by investment programs, which allow wealthy Russian investors and others to become citizens of foreign countries. Some nations are now re-evaluating these "golden passport" schemes, which they developed to boost their economies.

Climate change is compounding the drivers of displacement and international migration in Afghanistan, which has one of world's largest populations of internally displaced persons (IDPs).

The adoption of immigration measures by state and local governments can affect the sense of belonging not just for immigrants but also for the U.S. born, with impacts on individuals’ wellbeing, their engagement with others, and political participation. As the number of subfederal immigration measures has proliferated in recent years, research suggests this growth could have wider-ranging repercussions than commonly understood.
Beyond slowing global mobility dramatically, the COVID-19 pandemic sparked a major drop in asylum claims around the world, with the 1.1 million people seeking asylum in 2020 representing a 45 percent decline from the year before. This article examines the challenges to asylum processing during the pandemic, particularly for the UN High Commissioner for Refugees.
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.

The number of Central American immigrants in the United States has grown dramatically, amid political corruption, violence, and natural disasters in their native countries.

This article explores the administration's actions during its first three months.
