DHS/ALL/PIA-094 Migrant Protection Protocols (MPP) Case Request System
The Migrant Protection Protocols (MPP) program is a United States (U.S.) government program initiated in January 2019 pursuant to Section 235(b)(2)(C) of the Immigration and Nationality Act (INA). Under MPP, the United States returns certain citizens and non-Mexican nationals to Mexico while their U.S. removal proceedings are pending. The MPP Case Request System provides an avenue for individuals to initiate a review of their enrollment in MPP if they believe they should not be included in the program.
