Can You Be Asked to Prove Citizenship to Stay Registered to Vote?

Yes, in some states. Under the modified federal SAVE program at issue in this case, an election agency that uses it first tries to confirm your citizenship through federal records, and if that fails, the agency is required to ask you for proof. On September 25, 2026, the Supreme Court let a modified version of that program go back into operation while a lawsuit over it continues on appeal. The Court did not rule that the program is lawful. It ruled that the government is likely to win the appeal, so the program can keep running in the meantime.

What did the Supreme Court actually decide on September 25, 2026?

The Court granted a stay, which is different from a final ruling. In Department of Homeland Security v. League of Women Voters, No. 26A308 (Sept. 25, 2026), the Court's unsigned per curiam opinion put a June 22, 2026 district court order on hold. That district court order, from the U.S. District Court for the District of Columbia, had vacated (thrown out) the modified SAVE program after finding it violated the Social Security Act, the Privacy Act, and the Administrative Procedure Act. The stay means the modified program can operate again while the government's appeal moves through the U.S. Court of Appeals for the District of Columbia Circuit, and while any timely petition for Supreme Court review is pending. If the Court later declines to hear the case, the stay ends automatically. If it agrees to hear the case, the stay ends when the Court issues its final judgment. None of that has happened yet. Read the full opinion, including the dissent, at the Supreme Court's website.

The case reached the Court through several rounds of losses for the government. The district court sided with the plaintiff organizations on every claim, vacated the modified program, and denied the government's request to keep it in place during the appeal. A divided panel of the D.C. Circuit also denied a stay, with one judge dissenting. Only then did the government ask the Supreme Court to step in. To win a stay at that stage, the government had to show a reasonable probability that the Court would agree to hear the case, a fair prospect that it would reverse the district court, and a likelihood of irreparable harm if the stay were denied; where the case is close, the Court also weighs which side would be hurt more by getting it wrong. The per curiam opinion found those requirements met. As the dissent points out, the Court acted without full briefing or oral argument.

What is the SAVE program and how does the citizenship check work?

SAVE stands for Systematic Alien Verification for Entitlements. It has existed since 1986 as a way for federal, state, and local agencies to check the citizenship or immigration status of people applying for public benefits. In March 2025, an executive order directed the Department of Homeland Security (DHS) to put new systems in place allowing state and local authorities to verify the citizenship of registered voters and people registering to vote, and directed the Social Security Administration (SSA) to share its records with DHS for that purpose. Two months later, DHS launched the modified version at issue in this case. It added checks against SSA records, including Social Security numbers, and let agencies search multiple people at once instead of one at a time.

According to the per curiam opinion, a state or local election agency starts by uploading a person's first name, last name, date of birth, or full or partial Social Security number to the SAVE portal. SAVE forwards that information to SSA, which searches its own records for a match and sends its results to DHS, including the person's name, date of birth, full Social Security number, and citizenship status as SSA has it on file. SAVE then either confirms the person is a citizen or tells the agency to submit more information. If the program still cannot confirm citizenship, the opinion says the agency is required to contact the person directly and ask for proof of citizenship to register or to stay registered. As the majority describes it, the next step is a request for proof. The dissent, citing the district court's findings, adds that a state might strike a voter from the rolls if she does not provide that proof in time, so any notice you receive matters.

Why might my registration get flagged even though I am a citizen?

SAVE's answer depends on what SSA's records show, and the Court accepted that at least one plaintiff member's SSA record was out of date. The lawsuit that led to this stay was brought by several organizations, including the League of Women Voters, its local affiliates, and the Electronic Privacy Information Center. One of the individual members involved, identified in court papers as J. Doe 4, is a naturalized citizen registered to vote in Louisiana, a state that used the modified SAVE program. Court filings say SSA's records did not accurately show that she had become a naturalized citizen. The Court treated that kind of mismatch, and the burden of having to prove citizenship as a result, as a real injury, and on that basis found that the plaintiff organizations likely have legal standing to sue. Her situation shows that a person can be a citizen while an SSA record does not reflect it.

Does this mean my state will start checking my citizenship this way?

Not necessarily. Nothing in this ruling requires any state to adopt SAVE or to keep using it. The majority opinion mentions Louisiana's use of the modified program in the context of one plaintiff's case. Justice Jackson's dissent, citing the government's stay application, says 27 states currently use SAVE for voter verification, but it does not name them. If your state does not use SAVE, this program does not affect your registration directly. If you are unsure whether your state uses it, your state or local election office is the right place to ask; the U.S. Election Assistance Commission maintains a state-by-state directory of election offices for exactly that purpose.

What law did the Court say lets DHS request this information?

The majority pointed to a 1996 federal law, 8 U.S.C. §1373, which was enacted as part of the Illegal Immigration Reform and Immigrant Responsibility Act. Two parts of that law say that, notwithstanding any other federal, state, or local law, no government entity, official, person, or agency may prohibit or restrict the sending or receiving of citizenship or immigration information to or from DHS. A third part requires DHS to respond when a state or local agency asks it to verify someone's citizenship status. The majority read these provisions together as likely authorizing the information-sharing built into the modified SAVE program, even though the plaintiffs pointed to separate federal privacy laws that they say bar exactly this kind of disclosure. The Court called the plaintiffs' claims about those other statutes likely to fail on the merits, which is a preliminary assessment made for purposes of the stay, not a final ruling after full briefing and argument.

What are the dissenting justices concerned about?

Justice Jackson dissented, joined by Justices Sotomayor and Kagan. The dissent argues that the two sections of §1373 the majority relied on only stop officials from interfering with lawful information sharing; they do not, in the dissent's view, override specific confidentiality rules elsewhere in federal law, such as the Social Security Act's protection of Social Security numbers and related records. The dissent also says the majority looked only at the harm a stay would prevent for the government and did not weigh the harm to voters if the modified program keeps running, including the risk that recently naturalized citizens with outdated SSA records could be asked to prove citizenship they already have, or in some instances removed from the rolls. The dissent points to findings from the district court describing incidents in Texas in which one voter's registration was reportedly revoked without her knowledge and two others reportedly had to submit proof of citizenship to stay registered. Those are district court findings as the dissent describes them, and the majority opinion does not address them.

Could I be removed from the rolls right before the November election?

Federal law limits that risk, but the exact limits are not settled. The National Voter Registration Act requires states to complete any program meant to systematically remove the names of ineligible voters no later than 90 days before a federal primary or general election, and that window is already running ahead of the November 3, 2026 election. The majority said this moratorium limits the potential impact of the stay, and Justice Jackson's dissent says states cannot use SAVE to systematically strike people from the rolls in that period. The majority also said individualized inquiries are permitted under federal law during this period, meaning a state can still look into one voter's status and ask that voter for proof of citizenship if SAVE cannot confirm it. Whether the National Voter Registration Act bars states from running programs within those 90 days to cancel the registrations of voters who are not citizens is a separate question. The Court said it will consider that question in Republican National Committee v. Mi Familia Vota, No. 25-1017, and did not decide it here.

How does this relate to the ruling about state citizenship lists?

This case is separate from, but related to, an earlier order in Trump v. California, No. 26A124, decided August 24, 2026, which stayed a lower-court order and let the government move forward with a different executive order that, among other things, directs DHS to create and send states lists of their citizen residents. In that case the Court described the underlying order as an internal directive to federal agencies that neither requires nor forbids anything of anyone outside the executive branch, and it noted that states are not required to use those lists. Observed.org has a separate article on that ruling and its effect on mail-in ballots at Does Your Mail-In Ballot Count If It Arrives After Election Day?; this article focuses only on the SAVE citizenship-check program.

What should I do right now if I get a notice or I am a naturalized citizen?

Start by not ignoring any official notice, and treat your state or local election office as your first stop for anything specific to your own registration.

1. If you receive an official notice asking you to prove your citizenship to stay registered, read it carefully for the deadline and the list of acceptable documents, and respond before that deadline.
2. Gather documents that may show your citizenship, such as a U.S. passport, a Certificate of Naturalization, or a Certificate of Citizenship, and keep copies in case you need to submit them.
3. Contact your state or local election office directly if you have questions about a notice or about whether your state uses SAVE for voter verification; the Election Assistance Commission's state election office directory can point you to the right office.
4. If you were naturalized, be aware that, as one plaintiff in this case showed, an SSA record may not reflect a naturalization, and consider asking the Social Security Administration whether your record reflects your current citizenship status.
5. Watch for further developments in the case, since the underlying legal questions about the modified SAVE program are still being litigated on appeal and have not been finally decided.
