This legislation, titled the "Make the Migrant Protection Protocols Mandatory Act of 2025," aims to amend the Immigration and Nationality Act to require the implementation of the Migrant Protection Protocols (MPP). The bill specifically targets section 235(b)(2)(C) of the Act, changing the word "may" to "shall," thereby transforming the discretionary authority to apply MPP into a mandatory directive. This change would eliminate the executive branch's ability to suspend or discontinue the protocols, ensuring their consistent use. The Migrant Protection Protocols, commonly known as "Remain in Mexico," involve returning certain non-Mexican foreign nationals who arrive at the U.S. southern border to Mexico to await their immigration court hearings. By making these protocols mandatory, the bill seeks to establish them as a permanent policy for processing asylum seekers at the border.
