A federal judge in Manhattan has thrown out a Trump administration order that had halted green-card-track visa processing for people from 75 countries, ruling that the State Department reached well past its legal authority. In a 61-page opinion issued Friday, U.S. District Judge Jeannette A. Vargas of the Southern District of New York — appointed to the bench by former President Joe Biden — concluded that the internal directive ordering the freeze could not coexist with the system Congress built for deciding who receives an immigrant visa.
