Overview

• MSF’s “Rechazados” report documents how U.S. policy shifts under President Trump have left roughly 300,000 migrants stuck in Mexico since the CBP One app was shut down on January 20, 2025.
• Between January 2024 and May 2025, MSF-treated teams provided care to nearly 3,000 survivors of sexual violence and conducted almost 17,000 mental-health consultations along the migration corridor.
• Regional deterrence measures—including forced expulsions, arbitrary raids and deployment of Mexico’s Guardia Nacional—have driven many migrants into hiding and hindered humanitarian outreach.
• U.S. authorities report over 300,000 interior arrests in the first six months of the Trump administration and a 92% year-on-year drop in southern-border detentions in July.
• MSF calls on governments across the Americas to reverse externalization tactics, restore asylum pathways and guarantee migrants access to protection and essential services.
