The Department of Homeland Security’s immigration agency put on notice more than half a million immigrants who were paroled into the United States during the Biden administration to leave the country or face deportation, the agency told the Washington Examiner.

Between last Friday, March 28, and Monday, March 31, DHS agency U.S. Citizenship and Immigration Services notified more than 531,000 immigrants that their parole and employment documents would soon expire, a USCIS spokesperson confirmed in an email Friday.
