Graduate student unions are escalating contract demands tied to immigration enforcement risk, with Harvard’s graduate strike spotlighting protections for international students and similar bargaining underway at MIT. Unions are pushing universities to commit to legal and procedural safeguards—including limiting information sharing and expanding funds for legal expenses. At MIT, the graduate-student union is seeking remote-work flexibility for students affected by visa constraints and asking the university to promise not to comply with immigration agents without a judicial warrant. Similar contract provisions are cited as emerging from agreements at Cornell, Penn, and public universities in California and Maine. The pressure is driven by intensified enforcement actions described in the reporting, including arrests connected to pro-Palestinian activism and mass cancellations of student-visa records. Harvard’s union spokeswoman, Rochelle Sun, said federal actions over the past year made codified protections necessary.
