The Department of Homeland Security can now identify noncitizens on registered voter lists by accessing Social Security data following a 6-3 decision by the US Supreme Court. The ruling permits the Trump administration to resume using the Systematic Alien Verification for Entitlements, known as SAVE, to help states verify voter eligibility before the November midterms. Justices Sotomayor, Kagan, and Jackson dissented, while the majority found a 1996 federal law likely authorizes the access of citizenship records despite privacy restrictions. The Court stayed a lower court's June 22, 2026, order without deciding the final merits of the case.

Immediate implementation of the system is restricted by the National Voter Registration Act, which bars states from purging voters from rolls within 90 days of an election. Consequently, DHS is limited to conducting individualized citizenship checks rather than the mass bulk searches for which the expanded SAVE database was designed. Administration officials maintain the tool is essential for election integrity, while critics argue the database is flawed and could disenfranchise eligible naturalized citizens.
