REMAIN in Mexico Act of 2025

This bill would require the Department of Homeland Security to carry out the Migrant Protection Protocols (MPP) as described in a January 25, 2019 memo. Under MPP, people who arrive at the U.S.–Mexico land border and are not clearly admissible—including many asylum seekers—would be sent back to Mexico to wait while their U.S. immigration cases are decided, instead of staying in the United States during that time.

In short, it directs DHS to implement these protocols again, restoring a policy that the agency had previously stopped applying to new arrivals in 2021.

Key points:

• Who is affected: Migrants arriving by land at the U.S.–Mexico border who are not clearly admissible, including those seeking asylum.
• What changes: They would wait in Mexico while their U.S. immigration cases are pending, rather than remain in the United States.
• When: The bill orders DHS to implement MPP in line with the 2019 guidance memo.
