Foreign students in the US are experiencing anxiety as a result of a crackdown on visas and targeted detentions. Over 1,000 international students or recent graduates have had their visas revoked or legal statuses changed, with many unsure of the reasons behind these actions. The Trump administration has emphasized that visas are a 'privilege' that can be revoked at any time. The combination of targeted detentions and visa revocations has left campuses on edge, with students and faculty expressing fear and uncertainty about their own situations.
