The U.S. Department of Justice sued Maryland over a state law that allows some undocumented students to pay in-state tuition rates. DOJ said the policy violated federal commitments and alleged Maryland-based students saved about $9 million in tuition expenses between summer 2024 and spring 2025. Maryland’s criteria include attending and graduating from a Maryland high school, enrolling within six years of graduation, and providing proof of state tax filings by the student or legal guardians for two years during high school attendance. Students must also sign an affidavit promising to apply for permanent residency as they become eligible. The suit is the 13th state challenge DOJ has brought involving in-state tuition for undocumented students, with some states siding with DOJ and others, including Illinois and California, fighting the litigation. Minnesota won a case earlier this spring.
