Hundreds of international students in the United States have been instructed to leave the country after their F-1 student visas were revoked due to involvement in campus activism and online activity deemed 'anti-national.' The crackdown, led by U.S. Secretary of State Marco Rubio, targets students for physical participation in protests as well as sharing or liking critical social media posts. The State Department has developed an AI-powered app to detect and cancel visas of students supporting designated terrorist organizations. Students received emails instructing them to self-deport using the CBP Home App and warning of potential fines, detention, or deportation for remaining in the U.S. without legal status.
