This article offers data on the approximately 195,000 Afghan immigrants in the United States.

Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.

The Biden administration's court-ordered restart of the controversial Migrant Protection Protocols, known informally as the Remain in Mexico policy, puts it in the awkward position of reviving a program it is simultaneously still trying to end. The Trump-era program forced tens of thousands of migrants to wait out the duration of their U.S. immigration court hearings in Mexico and was only questionably successful at deterring unauthorized arrivals.

Mexico is facing a new reality: Rising migration from Central America, the reintegration of returning migrants, and protection of Mexicans in the United States.
