International students at Columbia University feel unsafe

International students and faculty at Columbia University are increasingly silent following a crackdown on pro-Palestinian protests. Federal agents have arrested two foreigners, including a student, and revoked another student's visa, causing fear among the international community. Columbia's Graduate School of Journalism reported a significant decline in participation from foreign students, who now feel unsafe expressing their views. Other universities are advising international students to be cautious about their public statements and online activity. The Trump administration's actions have raised concerns about free speech and the potential for more visa revocations. Recent arrests have prompted students across the U.S. to avoid political discussions, fearing repercussions for their immigration status.
