Biden v. Texas, 597 U.S. ___ (2022), was a United States Supreme Court case related to administrative law and immigration.

In December 2018 under the Trump administration, the United States Department of Homeland Security announced its promulgation of the Remain in Mexico policy, formally titled the Migrant Protection Protocols (MPP), which required asylum seekers to remain in Mexico while officials reviewed their case.

On June 30, 2022, the Supreme Court reversed the Fifth Circuit by a 5–4 vote and held that the federal government has the authority to revoke the Migrant Protection Protocols.

On December 15, 2022, U.S. district judge Matthew Kacsmaryk prevented the Biden administration from officially ending the program by ruling that the policy should stay in place while legal challenges play out.

[16] In February 2023, Mexico's Ministry of Foreign Affairs announced it rejects any efforts to reinstate the policy for asylum-seekers.
