Twenty-Two States Sue to Block Trump's Expanded Public Charge Rule Four Days Before It Takes Effect

California Attorney General Rob Bonta co-led a 22-state coalition that filed suit on September 14, 2026 to block the Trump administration’s expanded “public charge” rule, scheduled to take effect September 18. The rule would let immigration officials deny lawful permanent residency based on an applicant’s participation in Medicaid, SNAP, housing assistance, and other means-tested programs — a reach beyond the 2019 Cuccinelli rule that courts previously enjoined. San Francisco and Santa Clara County are plaintiffs in a separate, related municipal suit filed the same day (City of New York v. DHS, No. 1:26-cv-07982), not in the states’ case (State of New York v. DHS, No. 1:26-cv-07978, Judge Ronnie Abrams). The coalition argues the rule exceeds DHS’s statutory authority and violates the Administrative Procedure Act. (Corrected 2026-09-24: an earlier version said the coalition sought a temporary restraining order before the effective date. No TRO or PI motion appears on either docket through September 23, and the rule took effect September 18 without an order. See 2026-09-18–public-charge-rule-takes-effect-no-injunction-sought-sdny.)

The rule’s mechanism is the chilling effect rather than the denial rate, which is why the effective date matters more than the eventual merits ruling. Research on the first Trump administration’s 2020 version found roughly a quarter of adults in mixed-status families avoided benefits they legally qualified for — a disenrollment that operates on U.S.-citizen children in immigrant households and does not require a single adverse adjudication to work. DHS’s own 2025 proposal estimated $90 billion in decade savings through exactly that program disenrollment (2025-11-18–trump-reinstates-public-charge-rule-immigrant-wealth-test), which is the agency pricing the chilling effect as the policy’s yield rather than its side effect. The suit lands the same week as a Commerce proposed rule to exclude immigrants from 2030 census apportionment (2026-09-09–commerce-proposed-rule-exclude-immigrants-census-apportionment-2030) — two rulemakings whose shared premise is that presence in the country should not translate into presence in the count.
