A broad coalition of state governments, major cities, and counties has launched a coordinated legal challenge against the Trump administration over newly enacted immigration regulations. The revised federal measures significantly expand the criteria under which an immigrant’s use of public safety net services can be used to deny applications for permanent residency and entry visas.
Two separate lawsuits were filed on Monday in the U.S. District Court for the Southern District of New York. The legal actions specifically target the U.S. Department of Homeland Security along with U.S. Citizenship and Immigration Services, seeking to halt the policy before its scheduled implementation on Friday.
Under the disputed regulations, federal immigration adjudicators are granted wider latitude to weigh an applicant’s enrollment in various non-cash assistance programs when evaluating green cards, visa requests, and general admissions into the country. The rule permits officials to treat participation in vital initiatives—such as Medicaid, the Children's Health Insurance Program, food assistance, and subsidized housing—as evidence that an individual may become a "public charge."
Under federal immigration statutes, any applicant designated as a public charge—meaning someone deemed likely to depend on governmental assistance—faces mandatory grounds for inadmissibility. The new administrative framework dramatically shifts which benefit programs can trigger that determination.
The policy change effectively undoes a 2022 framework established under the Biden administration, which explicitly prohibited immigration authorities from factoring non-cash public benefits into public charge assessments. Defending the reversal, the Trump administration has maintained that the stricter guidelines are necessary to safeguard taxpayer funds and ensure that prospective immigrants remain fully self-sufficient.
State officials and policy analysts caution that the impending rules will cause severe spillover effects for mixed-status households across the country. Many families are anticipated to voluntarily disenroll from essential support systems, resulting in U.S. citizen dependents—particularly children—losing access to health care and social services to which they are legally entitled.
In their joint complaint, 22 states and the District of Columbia cited calculations from the Department of Homeland Security demonstrating that states could collectively lose an estimated $4.05 billion each year in federal transfer funding for Medicaid and the Children’s Health Insurance Program alone. The plaintiff states and the District of Columbia project their own direct losses from those health programs to be approximately $2.2 billion annually.
The multi-state legal challenge also details substantial fiscal damage to nutritional support networks. Nationwide, state programs stand to lose roughly $1 billion in federal funding under the Supplemental Nutrition Assistance Program, with the participating plaintiff jurisdictions absorbing an estimated $575 million share of those reductions.
The state-led lawsuit represents a geographically diverse coalition, including California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, Washington, and Wisconsin, alongside Washington, D.C.
Plaintiff states argue that the new regulatory language is rife with ambiguities that will force local governments into a severe financial predicament. State leaders assert they will inevitably be forced to fill the resulting funding voids out of their own municipal and state budgets, generating staggering unforeseen expenditures.
In addition to losing federal revenue and taking on heavier administrative obligations, state agencies warn of severe collateral damage to public health infrastructure. As families withdraw from preventive medical care, nutritional aid, and school lunch programs, states anticipate higher disease rates, poorer overall community health, and escalated emergency medical costs.
A companion lawsuit brought by local governments—including New York City, Chicago, San Francisco, Santa Clara County in California, as well as Seattle and King County in Washington—argues that the policy unlawfully sweeps away longstanding restrictions governing public charge designations. The municipal coalition projects that around 1.3 million residents across their jurisdictions, including roughly 600,000 children, could lose access to health coverage and public assistance.
New York City, which serves as the lead plaintiff in the local government lawsuit, calculates that the chilling effect will result in approximately 6,000 fewer primary care visits across the city each year as immigrant families avoid public clinics.
Highlighting the municipal impact, New York City Mayor Zohran Kwame Mamdani stated in a news release that the revised public charge rule is designed to alienate immigrant households from programs that have supported public health and nutrition for decades. Mamdani warned that eligible families will avoid doctors and social support out of fear, generating a damaging chilling effect that will ultimately burden all city residents.
The local government lawsuit also underscores threats to early childhood and educational programs, noting that families may preemptively pull children from subsidized educational services. The complaint highlights that approximately 19 percent of Seattle residents and 26 percent of King County residents depend on such low-cost or free education programs.
Together, the twin lawsuits represent a sweeping pushback from state and local authorities seeking to protect both their local operating budgets and the health and welfare of immigrant communities against the administration's expanded public charge restrictions.
