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.

This article, featuring findings from a large-scale survey involving more than 16,000 migrants in countries around the world, provides an overview of these challenges.
At his term's midpoint, President Joe Biden has relied on executive action to advance his immigration agenda more than his predecessors, including Donald Trump. Yet many of the changes to interior enforcement, humanitarian protection, and other areas have been overshadowed by the record pace of arrivals at the U.S.-Mexico border, which has presented the administration with major policy and operational challenges.

Between Brexit and COVID-19, Europe’s 31-country zone of free movement has been profoundly tested.

The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.
An unannounced sweep of 98 convenience stores by U.S. immigration authorities—resulting in the arrest of 21 unauthorized workers—may signal a new approach to worksite enforcement under the Trump administration, moving away from a strategy of paper-based audits that resulted in higher employer fines and fewer worker arrests. This article explores worksite enforcement over recent decades.
