Researchers from WOLA, the Kino Border Initiative, and Centro de Derechos Humanos Fray Matías de Córdova documented conditions for people deported from U.S. detention to Tapachula and Nogales, Mexico. Since February 2025 the U.S. has flown deported Mexican citizens to southern Mexico, with 6,045 arriving by July 28, 2025; in mid-April 2025 it largely stopped returning Mexicans across the land border in favor of flights, while more than 1,100 third-country nationals per month are now bused south to Villahermosa and Tapachula after land-border deportation. In Tapachula, Mexican deportees are held briefly in tent facilities, given about $100, and sent on long bus journeys without follow-up, while third-country nationals are taken to the Siglo XXI detention facility for undetermined periods. Many deportees, including those removed after decades in the U.S., are unable to document themselves because ICE fails to return passports and other belongings, leaving some—including stateless Nicaraguans—unable to legally leave Chiapas.
