The Trump administration has halted new visa interviews for international students, preparing for expanded social media screening as indicated in an internal State Department memo. This decision, signed by Secretary of State Marco Rubio, signals a broader crackdown on international students amid fears of national security threats, with significant implications for visa processing and higher education institutions. Critics argue that the move will deter prospective students and financially impact universities heavily reliant on foreign enrollment, despite claims of international students posing no threat.
