This bill, formally known as the REMAIN in Mexico Act of 2025 , directs the Secretary of Homeland Security to continue implementing the Migrant Protection Protocols . It explicitly overrides any other conflicting provisions of law to ensure these protocols remain in effect, thereby impacting the processing of migrants and asylum seekers at the border. The legislation mandates that the implementation of these protocols must align with the specific policy guidance issued by Secretary Nielsen on January 25, 2019. This ensures a consistent and defined approach to managing individuals seeking entry into the United States, requiring them to await their immigration proceedings in Mexico.
