The Trump administration recently told green card holders on the cusp of becoming U.S. citizens that their naturalization ceremonies had been canceled. Among those affected were immigrants who lined up at Boston’s Faneuil Hall last week and prepared to pledge allegiance to the United States. The group Project Citizenship told radio station WGBH, “officers were asking everyone what country they were from, and if they said a certain country, they were told to step out of line and that their oath ceremonies were canceled.”
