The U.S. government sued Virginia over a state program granting in-state tuition aid to unauthorized immigrants, escalating a legal fight that could reshape college access rules. Separately, legal and legislative moves in multiple states have prompted renewed scrutiny of Plyler v. Doe, the 1982 Supreme Court ruling that guarantees undocumented K‑12 students public education — developments advocates say could spill into higher-education policy and financial aid eligibility. University leaders and legal experts are watching whether federal litigation and state-level challenges will force admissions, compliance and enrollment offices to alter verification or aid practices for students without lawful status.
