Prem Raj Pun Magar, a Nepali national, filed a Petition for Writ of Habeas Corpus challenging the constitutionality of his detention in federal immigration custody. He is currently detained at the Rio Grande Processing Center. The petition names Miguel Vergara (ICE-ERO Field Office Director), Markwayne Mullin (Secretary of U.S. Department of Homeland Security), Todd Blanche (U.S. Attorney General), and the Warden of the Rio Grande Processing Center as respondents. On August 3, 2026, the U.S. District Court for the Southern District of Texas ordered respondents to file a response to the petition by August 10, 2026, with evidence from Magar's A-file. The court directed notification to the U.S. Attorney and ordered respondents to notify the court and Magar's counsel of any planned transfer or release.
