Make the Migrant Protection Protocols Mandatory Act of 2023

The Make the Migrant Protection Protocols Mandatory Act of 2023 (S 1479) would require the U.S. government to implement the Migrant Protection Protocols (MPP), commonly known as "Remain in Mexico," for certain asylum seekers encountered at the border. It amends Section 235(b)(2)(C) of the Immigration and Nationality Act by changing "may" to "shall," making MPP implementation mandatory rather than discretionary. The MPP requires asylum seekers to wait in Mexico while their U.S. immigration cases are processed, directly affecting individuals seeking asylum at the border who would otherwise be allowed to remain in the U.S. during proceedings. This policy change would standardize the use of MPP across all relevant cases without requiring additional legislative action.
