A coalition of dozens of state attorneys general, major cities, and county governments has launched a coordinated legal offensive against the federal government, seeking to block the Trump administration from enforcing newly expanded immigration restrictions tied to safety net utilization.
The dual lawsuits, which were submitted on Monday in the U.S. District Court for the Southern District of New York, name the U.S. Department of Homeland Security and U.S. Citizenship and Immigration Services as defendants. The plaintiffs are asking the court to halt the enforcement of the policy changes, which are scheduled to formally take effect this coming Friday.
Central to the legal battle is a sweeping revision of the federal "public charge" rule. Under the new directive, immigration adjudicators are granted broadened discretionary power to penalize immigrants seeking green cards, entry into the country, or particular visas if they utilize critical non-cash public benefits. These safety net programs encompass food assistance, housing support, Medicaid, and the Children's Health Insurance Program, commonly known as CHIP.
Under statutory immigration law, an assessment that a foreign national is likely to become a public charge serves as a primary ground for inadmissibility. While historical practices previously limited which benefits could trigger such determinations, the revived federal guidelines allow adjudicators to weigh basic healthcare and nutrition aid as evidence of potential dependency on the government.
This contested policy officially dismantles the regulatory framework established under the Biden administration in 2022, which explicitly shielded non-cash assistance programs from public charge evaluations. Defending the rollback, the Trump administration has maintained that reviving stricter standards is essential for safeguarding taxpayer money and guaranteeing that prospective permanent residents remain financially self-sufficient.
In the state-led lawsuit, a coalition comprising 22 states alongside the District of Columbia contends that the federal measure exceeds statutory authority. The participating states include California, New York, Illinois, Pennsylvania, Washington, Massachusetts, New Jersey, Michigan, Virginia, Oregon, Minnesota, Colorado, Maryland, Nevada, New Mexico, Connecticut, Hawaii, Maine, Delaware, Rhode Island, Vermont, and Wisconsin.
According to the states' legal filing, the financial ramifications for state-administered programs will be severe. Citing estimates prepared by the Department of Homeland Security itself, the complaint notes that states nationwide could lose approximately $4.05 billion each year in federal transfer funding specifically allocated for Medicaid and CHIP. Among the 22 plaintiff states and the District of Columbia, the anticipated loss in federal healthcare transfers is estimated at roughly $2.2 billion.
The anticipated wave of program disenrollments extends deeply into food security initiatives as well. The lawsuit highlights that nationwide state losses under the Supplemental Nutrition Assistance Program, or SNAP, could reach an estimated $1 billion annually. Out of that national figure, the plaintiff jurisdictions alone stand to lose an estimated $575 million in federal funding allocations.
State officials argue that the newly introduced regulations are riddled with pervasive ambiguities that leave local administrators in administrative disarray. Consequently, state governments claim they will ultimately be forced to step into the gap and absorb these staggering budget shortfalls using their own local tax dollars to prevent a total service collapse.
Beyond the direct budgetary impacts, the states emphasize that public agencies will inevitably shoulder substantial administrative expenses to navigate the altered requirements. Furthermore, as households avoid preventative medical care, essential nutrition assistance, and subsidized school lunch programs out of fear of immigration consequences, public health outcomes are expected to decline. Plaintiffs warn that this deterioration will spur increased disease transmission and ultimately drive up emergency medical expenses across local health systems.
In a parallel lawsuit filed in the same federal court, a coalition of prominent municipal and county governments has raised similar legal objections. The local government lawsuit is spearheaded by New York City, joined by Chicago, San Francisco, Seattle, California's Santa Clara County, and Washington's King County.
The municipal complaint asserts that the federal administration has acted unlawfully by overturning longstanding legal boundaries governing public charge assessments. Within these municipal jurisdictions alone, local officials estimate that roughly 1.3 million residents—including approximately 600,000 children—face the immediate threat of losing vital healthcare coverage, nutritional support, and related social services.
In New York City, officials project that the rule will lead to a reduction of approximately 6,000 primary care visits each year as immigrant families withdraw from clinical settings. New York City Mayor Zohran Kwame Mamdani condemned the federal policy in a public statement, arguing that the rule intentionally deters vulnerable families from accessing resources that have preserved public health for decades. Mamdani warned that the chilling effect will intimidate fully eligible individuals and citizen dependents, creating widespread social and economic repercussions across the entire city.
The coalition of local governments also documented serious disruptions to early education and child welfare. The suit emphasizes that fearful parents are expected to pull children out of subsidized or free educational offerings. In Seattle, where roughly 19% of residents depend on such programs, and in King County, where usage reaches 26%, the loss of participation could dismantle critical childhood development support.
Legal representatives and policy experts emphasize that mixed-status households—where immigrant parents reside with children who are United States citizens—will be particularly devastated by the rule. Because parents fear jeopardizing their immigration applications or chances of obtaining lawful permanent residency, they are expected to forgo benefits that their U.S. citizen children are fully and legally entitled to receive.
With the Friday implementation deadline looming, both the state and municipal coalitions are urging the federal court to intervene swiftly. The plaintiffs argue that unless an injunction is granted, the combination of widespread disenrollment, public health degradation, and billions of dollars in lost federal funding will inflict immediate and irreparable harm nationwide.
