Should states let undocumented high school graduates pay in-state college tuition?
Arizona state attorneys asked a federal judge to dismiss a Trump administration lawsuit that seeks to block the state's in-state tuition policy for undocumented students. The policy, approved by voters in 2022, applies to certain students who graduated from an Arizona high school.
Why it matters
For eligible Arizona students without legal immigration status, the policy is the difference between in-state and out-of-state tuition at public universities. The case could determine whether that tuition break survives, and the federal government argues the policy conflicts with a 1998 federal law and a recent executive order.
Proposition 308 lets students who graduated from an Arizona high school pay in-state tuition regardless of immigration status, and University of Arizona in-state undergraduate tuition is $13,906 a year compared with $43,068 for out-of-state costs. The Department of Justice puts alleged economic damages to Arizona universities at $10.5 million for the last school year.
The players
Trump administration
The federal executive branch that filed the lawsuit challenging Arizona's tuition policy and acts through the Department of Justice.
University of Arizona
A large public research university in Tucson whose published in-state undergraduate tuition is $13,906 a year.
Judge Murray Snow

The details
Under Proposition 308, eligible students must have graduated from an Arizona high school and meet a residency requirement that includes two years of physical presence in Arizona before graduation. The state's position is that the federal government cannot show a concrete, particularized injury, and that any alleged economic harm from reduced tuition falls on Arizona and its institutions rather than the United States. The federal challenge rests on a 1998 law that bars postsecondary benefits based on state residency for people not lawfully present unless the same benefit is available to citizens of any state, and on a 2025 executive order directing the Justice Department to act against such state benefits. Arizona's own courts have also weighed in: in 2018 the Arizona Supreme Court ruled that Proposition 300 precluded subsidized tuition for those not legally in the country, a backdrop to the 2022 measure.
Timeline
2012: The Obama administration created the DACA program.
2018: The Arizona Supreme Court ruled that Proposition 300 precluded subsidized tuition for those not legally in the country.
2022: Arizona voters approved Proposition 308.
2025: President Trump issued an executive order directing the Justice Department to act against states giving benefits to aliens not given to all citizens.
Earlier in 2026: The Trump administration sued to block Arizona's in-state tuition policy.
Education Landscape
The dispute sits within a long-running fight over whether states can extend in-state tuition to undocumented students, a question Arizona's own courts addressed in 2018 under Proposition 300. Arizona's policy is one of several state-level disputes in which federal courts have been ruling in cases tied to Trump administration actions, including rulings in Illinois, Texas and Nebraska.
Students who graduated from Arizona high schools and rely on in-state tuition should watch for any court ruling that could change what they pay at public universities. Families weighing their options can ask an Arizona university's financial-aid or admissions office how the lawsuit could affect future tuition for students in their situation.
The takeaway
The case will determine whether Arizona's Proposition 308 tuition rate stays in place, so it is worth following the court's ruling on the motion to dismiss. Students with questions about how tuition residency rules apply to them should bring them to a school's financial-aid office or another qualified adviser.
