The U.S. Supreme Court allowed President Donald Trump’s administration to remove the temporary legal status of hundreds of thousands of Venezuelan, Cuban, Haitian, and Nicaraguan migrants living in the United States, supporting the Republican president’s push to increase deportations.

The court stayed the order from U.S. District Judge Indira Talwani in Boston that halted the administration’s move to end the immigration “parole” granted to 532,000 of these migrants by former President Joe Biden, potentially exposing many of them to immediate removal while the case is heard in lower courts.

The ruling was unsigned and did not justify, as is common with emergency court orders. Two of the court’s three liberal justices, Sonia Sotomayor and Ketanji Brown Jackson, officially dissented.

Immigration parole is a type of temporary authorization granted by American law to enter the nation for “urgent humanitarian reasons or significant public benefit,” which allows grantees to live and work in the United States. Biden, a Democrat, used parole as part of his administration’s strategy for deterring illegal immigration along the U.S.-Mexico border.

Trump issued an executive order on January 20, his first day back in office, calling for the elimination of humanitarian parole programs. The Department of Homeland Security then attempted to terminate them in March, shortening the two-year parole awards. The government said that revoking parole would make it simpler to place migrants in an “expedited removal” procedure.
