A federal judge in Massachusetts has ordered the Trump administration to reinstate the temporary parole status of hundreds of thousands of migrants who entered the U.S. lawfully through the Biden-era CBP One app, ruling that the administration’s termination of their status violated federal procedures and exceeded DHS authority. The Trump administration had revoked parole en masse in 2025 without personalized notice, citing border security concerns, but the judge found this action unlawful and sided with immigration advocacy groups representing affected migrants. While the Department of Homeland Security opposes the ruling and plans to appeal, the decision restores legal protections for many migrants, though the full impact remains uncertain.
