The U.S. State Department has revoked more than 175,000 visas held by foreign nationals under President Donald Trump’s administration, marking a significant expansion of the government’s immigration and visa enforcement campaign. The State Department said Monday that visas were canceled for a range of reasons, including violations of visa conditions, criminal activity, threats against Americans, immigration fraud and national security concerns. The State Department said multiple people had their visas revoked after allegedly celebrating the assassination of conservative activist Charlie Kirk, including one person who reportedly said Kirk had “died too late.” The latest figure represents a sharp increase from January, when the State Department announced that more than 100,000 visas had been revoked, which was described as a record at the time. The surge in visa cancellations is part of the Trump administration’s broader immigration crackdown following his return to the White House.
