A federal appeals court has dealt the Trump administration another loss in its bid to revoke deportation protections and work permits for more than a half-million Cubans, Haitians, Nicaraguans and Venezuelans, many of them living in South Florida, who were granted entrance into the United States under a humanitarian parole program.

The U.S. Court of Appeals for the First Circuit, based in Boston, denied the administration’s request to stop a federal judge’s order blocking the Department of Homeland Security’s plan to end the parole program, which was implemented during the Biden presidency. In doing so, the appellate court found that “en masse termination” of the migrants’ parole is subject to review by the courts — contrary to the Homeland Security secretary’s view.
