International students and faculty in the US are feeling afraid to voice opinions or stand out on campus for fear of getting kicked out of the country. The Trump administration's crackdown on pro-Palestinian protesters at Columbia University has caused apprehension among international students and faculty. Federal immigration agents have arrested two foreigners and revoked the visa of another student, leading to a chilling effect on discourse and scholarly research. The arrests and visa revocations send a message that disagreeing with the Trump administration could result in deportation.
