The U.S. Department of Justice sued Colorado over its in-state tuition policy for undocumented students, continuing an administration push targeting state financial-aid eligibility. Colorado’s 2013 law allows undocumented students to qualify for in-state tuition if they meet specific residency requirements or graduated from a Colorado high school. DOJ argued the policy unlawfully extends lower tuition rates and state financial aid to students who are not eligible for those benefits on the same terms as U.S. citizens. DOJ also contends the approach encourages illegal immigration—an argument that states and local officials have rejected. While Colorado became the latest state challenged, the lawsuit aligns with a broader pattern: DOJ has targeted at least 14 states, with some cases ending quickly and others producing mixed rulings in federal court.
