In-State Tuition Just Got Sued: DOJ's Case Against New Mexico
Aaron Elinoff · Managing Partner, Novo Legal Group · Colorado Bar #46468 · Immigration & Civil Rights
The federal government sued New Mexico this week over its in-state tuition law for immigrant students, filing a complaint in U.S. District Court that seeks to permanently block the state from offering reduced tuition or financial aid to any student without regard to immigration status. The lawsuit targets Senate Bill 582, a 2005 law that has for two decades extended in-state rates, scholarships, and grants to students who attended a New Mexico high school for at least one year, graduated from a state high school, or earned a GED in the state.
New Mexico is one of four states the Department of Justice sued Thursday. The others are Arizona, Oregon, and Washington. With those four complaints, the DOJ has now sued 21 states over similar in-state tuition programs for undocumented students.
The stakes for immigrant students in New Mexico are real. Nothing changes today. A permanent injunction requires a federal judge to rule on the merits, and New Mexico has not yet responded to the complaint. A federal judge in Minnesota recently dismissed a parallel DOJ lawsuit against that state. Courts in other in-state tuition cases have reached different conclusions.
This post explains what the DOJ filed, what SB 582 actually does, what the federal legal argument is, how the 21-state pattern has developed, and what current and prospective immigrant students in New Mexico should do while the litigation moves forward.
Three facts, fast
- The DOJ sued New Mexico, Arizona, Oregon, and Washington on August 27, 2026 over state laws that let immigrant students pay in-state tuition.
- The New Mexico law at issue is Senate Bill 582 from 2005. It extends in-state rates, scholarships, and grants to state residents who attended a New Mexico secondary school for at least one year, graduated from a state high school, or earned a GED in the state.
- Nothing changes for current students today. A federal judge in Minnesota dismissed the DOJ's parallel case against that state. Similar suits are pending in more than a dozen other states.

What the DOJ filed against New Mexico
The United States filed its complaint against the New Mexico Higher Education Department in U.S. District Court on Thursday, August 27, 2026. The complaint asks the court to declare Senate Bill 582 preempted by federal law and to enter a permanent injunction prohibiting the state from enforcing the law's tuition and financial aid provisions for any student not lawfully present in the United States.
The DOJ's press release framed the New Mexico complaint as one of four filed the same day, alongside parallel complaints against Arizona, Oregon, and Washington. Associate Attorney General Stanley E. Woodward, Jr. announced the filings, stating that Congress has prohibited states from "placing aliens over citizens." Assistant Attorney General Brett A. Shumate, who leads the Justice Department's Civil Division, described the matter as a "simple matter of federal law."
The complaints against all four states share a common theory: that each state has offered postsecondary education benefits to undocumented immigrants on the basis of state residence while denying the same benefits to U.S. citizens who reside in other states, and that federal law prohibits that arrangement.
What New Mexico's in-state tuition law actually does
Senate Bill 582 was passed by the New Mexico Legislature in 2005 with the sponsorship of then-Senator Cynthia Nava, D-Doña Ana, a former superintendent of Las Cruces Public Schools. The bill passed with substantial bipartisan support, 28 to 3 in the state Senate and 41 to 26 in the House.
The law's operative provision extends in-state tuition, scholarships, and state financial aid to any resident of New Mexico who meets one of three eligibility paths: attended a New Mexico secondary school for at least one year, graduated from a New Mexico high school, or earned a GED certificate in the state. The statute expressly provides that these benefits are available "regardless of immigration status."
In practical terms, SB 582 has meant that a student who grew up in New Mexico, attended a New Mexico high school, and stayed in the state for college has been able to pay resident tuition rates and access state scholarships at institutions like the University of New Mexico, New Mexico State University, and the state's community colleges, without regard to whether the student is a U.S. citizen, a lawful permanent resident, a DACA recipient, or a student without any current lawful immigration status.
The law has now been on the books for 20 years. Thousands of students have relied on it.
The federal legal argument
The DOJ's complaints rest on a federal statute enacted in 1996 as part of the Illegal Immigration Reform and Immigrant Responsibility Act. That statute, codified at 8 U.S.C. § 1623, provides that an alien not lawfully present in the United States is not eligible on the basis of residence in a state for any postsecondary education benefit unless the same benefit is available to citizens or nationals of the United States on the same terms, "without regard to whether the citizen or national is such a resident."
The DOJ reads that statute to bar a state from extending in-state tuition to undocumented immigrants on residence-based terms unless the state also offers the same in-state tuition rate to every U.S. citizen in every other state. Because New Mexico charges out-of-state U.S. citizens higher non-resident tuition, the DOJ argues, extending resident-rate tuition to an undocumented New Mexico student violates the federal statute.
New Mexico is likely to argue that SB 582's eligibility criteria are not residence-based within the meaning of § 1623. The statute conditions benefits on attendance at a New Mexico secondary school, graduation from a New Mexico high school, or completion of a GED in the state. Those are educational criteria applied to any qualifying student, and the statute makes those same criteria available to any U.S. citizen who meets them, in any state, without regard to current residence. Under that reading, the law does not condition benefits on state residence at all.
This is the same argument other states have raised in defense of similar statutes. Courts have not uniformly accepted or rejected it. The outcome in New Mexico will turn on how the district judge reads the statute, the legislative history of § 1623, and the specific text of SB 582.
The 21-state pattern
The New Mexico complaint is not an isolated action. Since President Trump's April 2026 executive order directing the Justice Department to challenge state laws that extend in-state tuition to undocumented students, the DOJ has filed a rolling series of complaints against states with similar programs.
Early filings targeted Texas, Kentucky, Oklahoma, and Nebraska. Later rounds added Massachusetts and Rhode Island, then Connecticut, New York, and Vermont. As of Thursday, August 27, 2026, the DOJ has sued 21 states in total.
Outcomes have varied. Texas entered into a consent decree quickly, effectively ending its in-state tuition program for undocumented students. Kentucky, Oklahoma, and Nebraska each resolved their cases on terms favorable to the federal government. Other cases remain in various stages of litigation, from motion practice to discovery.
The most notable pushback so far came from Minnesota.
What the Minnesota dismissal tells us
A federal judge in Minnesota recently dismissed the DOJ's suit against that state, ruling that Minnesota's public universities may continue offering in-state tuition and scholarships to immigrants without current lawful status. The dismissal does not bind courts in other jurisdictions, but it establishes a serious counter-precedent that state defendants in New Mexico, Arizona, Oregon, and Washington will likely cite.
The takeaway is straightforward. The DOJ has not won every one of these cases, and the legal question is not settled. Different courts have reached different conclusions on how § 1623 interacts with state laws that use educational, rather than residence, criteria. New Mexico's response to the complaint will matter, and the reasoning of the New Mexico judge assigned to the case will matter.
What happens next in the New Mexico case
The DOJ's complaint sets a deadline for New Mexico to respond. The state will likely file either a motion to dismiss or an answer within the coming weeks. If the state moves to dismiss, the court will hear argument and rule before the case moves into discovery.
Realistic timeline expectations:
- Weeks to months: New Mexico responds. Any motion to dismiss is briefed and argued.
- Months: The district court issues a ruling on the motion to dismiss. If the case survives, it moves into discovery.
- Months to more than a year: The parties conduct discovery, brief cross-motions for summary judgment, and argue the merits.
- After the district court rules: An appeal to the Tenth Circuit is likely from whichever side loses. That appeal alone could take a year or more.
Throughout this timeline, the challenged provisions of SB 582 remain in effect unless a court enters a preliminary injunction. The DOJ has not sought a preliminary injunction in these tuition cases in most instances, and there is no reason to expect a different pattern here.
What this means for current and prospective students
The most important point for students and families is this: as of today, nothing about the in-state tuition benefit under SB 582 has changed.
- Currently enrolled students: Your in-state rate continues. Any scholarships or state financial aid you already receive continue to disburse under the terms of the applicable award.
- Fall 2026 registration: Continues under existing rules. Students who qualify under SB 582 continue to qualify.
- Applications for spring 2027 and beyond: Continue to apply as you normally would. The application, admission, and financial aid processes remain unchanged during the pendency of the litigation.
- DACA recipients: DACA status has always been distinct from lawful status for immigration purposes, but SB 582's eligibility criteria do not turn on DACA. A DACA recipient who meets the educational criteria of SB 582 has always qualified on that basis.
- If the DOJ eventually wins: Even a favorable district court ruling for the federal government would likely not take immediate effect during any appeal. A court order changing tuition eligibility would need to specify an effective date, and any state institution's response would need time to implement.
None of this substitutes for individual advice. Every family's situation is different, and immigration status, financial aid packages, and enrollment timing interact in ways this post cannot evaluate.
What we don't know yet
Several important questions remain open:
- How the assigned federal judge will read § 1623 in relation to SB 582's educational-criteria structure.
- Whether the DOJ will seek a preliminary injunction that could change tuition eligibility mid-case.
- Whether New Mexico's response will raise a facial challenge to § 1623 itself, arguing that Congress cannot displace state authority over public education funding in this way.
- How the parallel cases against Arizona, Oregon, and Washington develop, and whether a circuit split emerges that could reach the Supreme Court.
- Whether Congress or the executive branch takes additional action, including new legislation such as the Put American Students First Act that has been introduced to codify the federal position.
We will publish updates as material developments occur.
What to do now
If you are a current New Mexico college student who qualifies under SB 582:
Continue your enrollment. Confirm with your institution's financial aid office that your fall 2026 aid disburses on schedule. Save documentation of your current tuition classification and any award letters in case eligibility rules change later. If you have questions about your immigration status independent of tuition, speak with an immigration attorney.
If you are a prospective New Mexico college student who would qualify under SB 582:
Apply as you normally would. Complete the state financial aid application on schedule. Do not delay applications based on the pendency of this litigation. If your family is weighing New Mexico institutions against out-of-state options, factor the litigation risk into a longer-term planning conversation, but recognize that the immediate benefit of SB 582 remains available.
If you are a family with a high school student in New Mexico:
Nothing in this lawsuit affects K-12 education. Your student's Plyler v. Doe right to public K-12 education is unaffected. Continue planning for postsecondary education. Talk to your student's college and career counselor about the current landscape.
If you are an immigration attorney or advocate advising students in New Mexico or in Arizona, Oregon, or Washington:
Track the docket in each of the four newly filed cases. Note whether any state moves for preliminary injunctive relief. Advise clients that the current benefit remains available and that the litigation is likely to take many months to resolve.
Frequently asked questions
Does this lawsuit affect DACA recipients?
Indirectly. SB 582's eligibility is not tied to DACA status. A DACA recipient who attended a New Mexico high school for at least one year, graduated from a New Mexico high school, or earned a GED in the state has always qualified for in-state rates on those educational grounds. The DOJ's argument reaches all students without current lawful status, which includes DACA recipients under the DOJ's reading.
What if I am already receiving state financial aid?
Aid you have already been awarded continues to disburse under the terms of the award. Contact your institution's financial aid office to confirm the current status of your package.
Does the lawsuit affect private colleges in New Mexico?
No. SB 582 governs tuition at state public institutions. Private colleges set their own tuition and financial aid policies.
Can I still apply for the spring 2027 semester?
Yes. Applications and financial aid processing continue on their normal cycle.
What about students in Arizona, Oregon, and Washington?
Each of those three states was sued the same day and will litigate its own case. The immediate practical effect is the same. Benefits under existing state law continue until and unless a court orders otherwise.
What is 8 U.S.C. § 1623?
It is a provision of federal immigration law enacted in 1996. It restricts states from offering postsecondary education benefits to persons not lawfully present in the United States on the basis of residence, unless the same benefits are made available to U.S. citizens on the same terms, without regard to citizens' state of residence. The scope and interpretation of § 1623 in relation to state laws that use educational criteria, rather than residence criteria, is the central question in this line of litigation.
