Graduate-student unions escalated contract demands aimed at protecting international students amid immigration enforcement pressure. Harvard’s graduate students went on strike, and MIT’s graduate student union is beginning negotiations seeking remote-work flexibility for visa-restricted students and an institutional pledge not to comply with immigration agents without a judicial warrant. The reporting ties the bargaining focus to federal actions that targeted noncitizen students, including court action by Harvard to block an enrollment authority ban and DHS pressure to share disciplinary information. At Harvard, union leaders are also pushing to increase a legal-expense fund from $30,000 to $225,000. The development matters for universities because it links labor contract terms, student visa operational decisions, and data-handling practices to enforcement risk—creating new compliance and governance obligations for graduate schools.
