DOJ Sues Colorado Over Undocumented Student Tuition

The U.S. Department of Justice filed a lawsuit against the state of Colorado on July 28, 2026, challenging a state law that provides in-state tuition rates to undocumented students. This legal action centers on the interpretation of federal immigration law and its implications for state-level educational policies. The lawsuit, filed in the U.S. District Court for the District of Colorado, argues that Colorado's law, which allows undocumented students who have attended a Colorado high school for at least three years and graduated or earned a GED to qualify for in-state tuition, conflicts with federal statutes. Specifically, the Department of Justice contends that the Colorado law violates Section 505 of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA). This federal provision generally prohibits states from providing any postsecondary educational benefit on the basis of state residency to individuals who are not lawfully present in the United States, unless such benefit is made available to all citizens of the state without regard to their immigration status. The lawsuit asserts that Colorado's law creates such a benefit for undocumented students, thereby contravening federal law. The state of Colorado, through its Attorney General's office, has defended the law, asserting that it aligns with the state's commitment to educational equity and that it does not violate federal law. Proponents of the law argue that it is essential for providing opportunities to students who have grown up and been educated in Colorado, regardless of their immigration status. They emphasize that these students are integral members of the community and that denying them access to affordable higher education would be detrimental to both the individuals and the state's future workforce. The legal challenge raises significant questions about the balance of power between federal and state governments in setting educational policy, particularly concerning immigration. The outcome of this lawsuit could have far-reaching implications for similar laws in other states that aim to support undocumented students in accessing higher education. The Department of Justice's action signals a potential shift in federal enforcement priorities regarding state-level benefits for undocumented immigrants. The specific provisions of Colorado's law under scrutiny include requirements for students to have attended a Colorado high school for at least three years, graduated or obtained a GED, and filed an affidavit indicating their intent to legalize their immigration status. The lawsuit does not seek to overturn the entire law but rather to prevent its application to undocumented students, arguing that it constitutes an unlawful state-sponsored benefit. The legal battle is expected to involve extensive arguments regarding the interpretation of IIRIRA and the scope of state authority in educational matters. The Department of Justice's filing is a direct challenge to Colorado's long-standing policy, which has been in place for several years and has benefited thousands of students. The state has maintained that the law is consistent with federal law by offering the benefit to all students who meet the residency and educational requirements, regardless of their immigration status, as long as they are pursuing higher education within the state. However, the DOJ's interpretation focuses on the 'lawful presence' aspect of the federal statute. This case underscores the ongoing tension between federal immigration enforcement and state efforts to support immigrant populations through educational access.
