International students at Columbia fear repercussions for activism

International students at Columbia University are increasingly silent amid a crackdown on pro-Palestinian protests. Federal agents have arrested two foreigners, including a student, and searched residences of other students, raising fears about immigration consequences. The arrests have created a chilling effect on campuses nationwide. Many international students and faculty feel unsafe expressing their views, fearing deportation or visa revocation. Some universities are advising caution regarding public statements and online activity. The situation escalated after the arrest of activist Mahmoud Khalil, with more visa revocations expected. Immigration authorities have also detained other students linked to protests, prompting concerns about free speech and the treatment of non-U.S. citizens in academic settings.
