Countries such as Nepal and the Philippines have grown reliant on sending workers abroad to earn money, skills, and connections that help boost their economies. In these cases, emigration has become a way for governments in the Global South to offer their citizens access to social services and protections that they could not otherwise provide. This article details the emergence of this new mode of state-society relations.

The Afghan immigrant population in the United States has grown dramatically since 2010, and particularly since the 2021 withdrawal of U.S. forces from Afghanistan. Most Afghans who obtained a green card in recent years have done so through the Special Immigrant Visa (SIV) program, reserved for interpreters and other Afghans who worked with the U.S. government. This article offers data on the approximately 195,000 Afghan immigrants in the United States.
The number of Tibetan refugees in India, Nepal, and Bhutan has been on a steady decline since the mid-2000s, posing a threat to the future of an exile community that has developed a robust governance, cultural, educational, and religious structure. While the Tibetan government-in-exile has become a model for displaced communities, a series of factors have contributed to the shrinking population in South Asia, as this article describes.

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.

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.
Can haphazard, unplanned climate displacement be turned into voluntary, safe migration? Projects explicitly aimed at addressing internal and international climate migration are rare, but development organizations increasingly are turning their attention to supporting them. This article catalogues climate mobility projects around the world and examines their primary goals, whether to support the movement or stay of people or help at destination.
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.

The Taliban’s takeover of Afghanistan has prompted fears of a rollback of human rights and a new refugee crisis. This article examines the prospects for possible future Afghan displacement in the region and beyond by looking at the last four decades of forced migration from Afghanistan and new factors that could determine what happens now that the U.S. military and its allies have pulled out.
Gang violence is a major driver of migration, particularly from Central America to the United States. But governments on both sides often rely on outdated and static understandings of gangs and their membership. This article explains the history of groups such as MS-13 and Barrio 18 and why they are relevant for immigration policy.
Trade between China and Africa has ballooned, reaching nearly $200 billion in 2019. Yet many of the migrant entrepreneurs and traders who contribute to this relationship live in precarious positions in both China and Africa. This article explores the informal systems navigated by many migrants in both regions and the policies that drive the precarity in which many of these traders live.
Canada is one of the world’s top countries for resettling refugees, relying on individual Canadians and nonprofit groups—not the government—for much of this resettlement. This article examines Canada’s unique system of private sponsorship, which has become a model for other countries as they seek to increase capacity for refugee resettlement at a time of record global need.
Countries across the globe have considered novel ways for diasporas to directly invest in national development by purchasing diaspora bonds. Israel has raised billions through its Israel Bonds over the last 70 years, and India has had some success with its diaspora bond efforts. But other countries have faced challenges, as this article explores.

While much attention has been paid to recent Central American arrivals at the U.S.-Mexico border, nearly half of the approximately 3.5 million Central Americans resident in the United States in 2017 arrived before 2000.

Discover more about this population in this data-rich article.

Nearly 22 million immigrants—about half of the overall immigrant population—were naturalized U.S. citizens in fiscal year 2017. In the same year, more than 707,000 immigrants became U.S. citizens.

The United States has historically been the top country for refugee resettlement, but was surpassed in 2018 by Canada amid record cuts to admissions by the Trump administration. Approximately 22,500 refugees were resettled in the United States during fiscal year 2018, as well as 26,500 asylees. This article examines where these newcomers came from and many other characteristics, including religious affiliation, age, and gender.

As the Trump administration moves to be able to indefinitely detain parents and children intercepted at the U.S.-Mexico border, whether illegal border crossers or asylum seekers, recent apprehension trends and history suggest hardline policies might not be a slam-dunk deterrent with a Central American population often driven by the desire to escape gang or other violence, as this Policy Beat explores.
With the #AbolishICE movement catching fire among some on the left, critics of the Trump administration's immigration policies have seized on U.S. Immigration and Customs Enforcement (ICE) as their main target—even condemning it for actions taken by other agencies. This article explores the evolution of ICE and resistance to it, as well as actions taken by the agency itself that have made its mission even more controversial.
Though the Supreme Court handed the Trump administration a major victory by upholding its much-contested travel ban, less noted has been the fact that the ruling left an opening for future challenges to the policy of barring groups of foreign nationals from the country. This Policy Beat explores the evolution of the travel ban, the justices' arguments for and against, and changes in visa grants from travel-ban countries.
Frustrated by an uptick in migrant apprehensions at the U.S.-Mexico border in recent months, the Trump administration unveiled a set of sweeping changes, aiming to prosecute for federal immigration crimes every migrant apprehended crossing illegally. The policy will likely be hindered by legal challenges and capacity limitations, as this article explores.
Seizing on reports of a migrant “caravan” making its way northward through Mexico, President Donald Trump called for up to 4,000 National Guard troops to deploy to the Southern border. Although previous presidents took similar action in response to upticks in violence and apprehensions, the picture at the border today differs on several metrics. This article examines how the deployment compares to those under Presidents George W. Bush and Barack Obama.
