Roberto López Falcón, a fifth-grade ESL teacher at Hart Elementary School in Austin ISD who was named Campus Teacher of Promise in January 2025, was detained by ICE on September 3, 2025, at an immigration check-in appointment in San Antonio. Falcón, 34, a Cuban national who entered the U.S. without inspection near San Luis, Arizona on March 22, 2022, was released by Border Patrol on an order of recognizance pending an immigration hearing. He was held at the Karnes County Immigration Processing Center to continue his immigration proceedings and remained in custody as of November 2025. At least four additional Austin ISD employees—a bus driver and lunchroom workers—were also detained in the same ICE enforcement sweep. Education Austin, the largest union representing district teachers and staff, confirmed the detentions. Falcón's family reported being devastated by his arrest and struggling without his presence and support.
