Graduate student unions escalated contract demands around immigration protections as U.S. enforcement intensified, with the Harvard Graduate Students Union using the recent strike as leverage. The union’s bargaining positions include requiring protections for international students at risk, including remote-work flexibility tied to visa constraints and commitments not to comply with immigration agents without a judicial warrant. Reporting indicates the MIT Graduate Student Union is pursuing similar terms while negotiations begin, and that agreements at Cornell, Penn, and some California and Maine public universities include provisions formalizing support for immigrant and noncitizen students. The issue has also surfaced amid arrests of graduate students at Columbia and Tufts and a broader campaign involving student-visa record actions. Rochelle Sun, a Harvard doctoral student and spokeswoman for the Harvard Graduate Students Union, linked contract changes to federal actions targeting noncitizen students in the past year. Negotiators are also seeking limits on the university’s sharing of student information and higher legal expense funds for noncitizen students.
