The Department of Justice sued Colorado over the state’s in-state tuition policy for undocumented students, according to the story. The legal challenge is part of a broader DOJ effort targeting state eligibility rules; the story says DOJ has filed similar suits against 14 states and that some quickly agreed to end their policies. Colorado’s law, passed in 2013, allows undocumented students to qualify for in-state tuition if they meet residency requirements or have graduated from a Colorado high school. DOJ argues the policy is unlawful because it extends lower tuition rates and state financial aid to undocumented students that are not available to out-of-state U.S. citizens, and it says the policy effectively subsidizes illegal immigration. The story also notes political blowback in Colorado, including criticism from Democratic officials and lawmakers who previously supported the policy. The outcome could affect campus affordability strategies, enrollment planning, and state-by-state compliance risk assessments for public colleges.
