""YOU'LL HAVE TO GET THROUGH ME!" — Mamdani Draws The Line As Trump's Immigration Fight Hits New York!"

YOU’LL HAVE TO GET THROUGH ALL OF US — Mamdani Takes Trump’s New Public Charge Rule to Court

New York City is leading a coalition of local governments against a federal immigration rule set to take effect September 18, turning a long-running dispute over benefits, immigration and federal authority into a direct legal confrontation.

New York City’s immigration conflict with the Trump administration has moved from political confrontation into federal court, with Mayor Zohran Mamdani leading a coalition of cities and counties seeking to block a new “public charge” rule scheduled to take effect on September 18.

Standing at City Hall alongside New York Attorney General Letitia James and immigrant advocates, Mamdani cast the lawsuit as both a legal challenge and a defense of immigrant New Yorkers who may fear that using public services could jeopardize their ability to remain in the United States. Near the end of his remarks, he returned to a line that has become central to his approach to federal immigration enforcement: “Immigrants are New Yorkers,” he said, adding that “to get to any of us, you will have to get through all of us.”

The language was dramatic, but the immediate fight is highly specific. On July 20, the Department of Homeland Security published a final rule rescinding the Biden administration’s 2022 regulatory framework for determining when an immigrant may be considered likely to become a “public charge.” The new rule is scheduled to apply to applications for admission made on or after September 18 and to adjustment-of-status applications postmarked or electronically submitted on or after that date.

The change does not create an automatic rule under which receiving one particular benefit necessarily causes an immigration application to be denied. Instead, DHS says the rescission restores broader discretion to immigration officers to evaluate an applicant’s circumstances on an individualized basis. Under the final rule, officers may consider mandatory statutory factors, the receipt of means-tested public benefits and other case-specific information they determine is relevant to assessing whether a person is likely at any time to become a public charge. DHS has emphasized in the rulemaking record that receiving a means-tested benefit is not, by itself, outcome-determinative.

That distinction is central to the legal and political fight. New York City, New York State and other plaintiffs argue that removing the definitions and guardrails contained in the 2022 rule gives federal immigration officers too much discretion and leaves families unable to know in advance what assistance might be held against an applicant. The administration argues that the 2022 approach was too restrictive and prevented officers from carrying out the public-charge provision in the way Congress intended.

The dispute has produced two separate lawsuits in the U.S. District Court for the Southern District of New York. Mamdani’s administration is leading a municipal coalition that includes Chicago, the City and County of San Francisco, Santa Clara County, Seattle and King County, Washington, along with the Public Rights Project. In a parallel case, Attorney General James is leading a coalition of 21 other states and the District of Columbia.

Both challenges seek to stop the new policy from taking effect, though they are brought by different groups of governments asserting different forms of harm. The local-government suit argues that uncertainty around the rule will discourage eligible residents from using health, nutrition and other services, shifting costs to cities, hospitals and community institutions. The states’ lawsuit similarly argues that the rule is unlawful and could destabilize programs administered by state governments.

The plaintiffs contend that DHS acted arbitrarily and capriciously under the Administrative Procedure Act, exceeded its statutory authority and departed from the historically narrower understanding of who should be considered a public charge. The administration rejects that interpretation and says federal law has long allowed immigration authorities to assess whether applicants are likely to become dependent on public resources.

The public-charge concept itself is not new. American immigration law has used versions of the term for more than a century, and current federal law directs immigration authorities to consider factors including age, health, family status, assets, resources and financial status when determining whether certain applicants are likely to become a public charge. The political fight has centered on how broadly that concept should be interpreted and what forms of assistance should matter in the analysis.

During President Donald Trump’s first term, his administration adopted a 2019 rule that expanded the range of benefits considered in public-charge determinations. The policy generated extensive litigation and criticism from states, cities, immigrant-rights groups and health providers, who said it caused families to withdraw from public programs even when they remained legally eligible. The Biden administration later abandoned that approach and in 2022 adopted a narrower regulation.

The Trump administration’s 2026 rule reverses that direction. DHS says the 2022 regulation “straitjacketed” immigration officers and did not properly reflect congressional policy favoring self-sufficiency. The final rule removes the 2022 regulatory definitions and framework and returns greater weight to case-by-case judgment, with USCIS guidance intended to inform officers as they assess the totality of an applicant’s circumstances.

For Mamdani and James, that discretion is precisely the problem. At the City Hall announcement, officials argued that families may not know whether using Medicaid, food assistance, housing support or other income-based programs could later be viewed negatively in an immigration case. James said the new framework is so broad that immigrants in mixed-status households may fear using benefits for U.S. citizen family members, even when those family members are independently entitled to the assistance.

The administration disputes the plaintiffs’ characterization. In response to the lawsuits, a DHS spokesperson accused “sanctuary states” and Democratic officials of trying to preserve public-benefit use by noncitizens and argued that immigration policy should promote self-reliance rather than dependence on taxpayer-funded assistance. The White House has similarly framed the issue as part of Trump’s broader pledge to put U.S. citizens first and tighten immigration rules.

That means the lawsuits are not merely about technical wording in an immigration regulation. They sit at the intersection of two competing views of public policy: one emphasizing the government’s authority to consider financial dependence when deciding who may obtain permanent status, and another emphasizing the risk that vague or expansive standards will frighten eligible families away from health care, food assistance and other services.

Mamdani’s administration has responded by telling New Yorkers not to abandon benefits simply because of fear surrounding the new rule. City officials have specifically urged residents who rely on programs such as SNAP, Medicaid, WIC or TANF not to disenroll without first consulting a trusted legal provider. The Mayor’s Office of Immigrant Affairs has also been organizing community forums, trainings and legal-service outreach in anticipation of the rule’s effective date.

The city’s message is partly designed to address what officials call a “chilling effect.” That term describes a situation in which people avoid a lawful service because they fear a separate consequence, even when the consequence is uncertain or may not actually apply to them. In the public-charge context, city and state officials say the concern extends beyond immigrants directly subject to the rule because households can include U.S. citizens, lawful residents and people with different immigration classifications.

The scope of the rule is also important. Public-charge inadmissibility does not apply to every immigrant or every immigration category. Mamdani noted that U.S. citizens are not subject to the rule and that people seeking certain humanitarian protections, including asylum, are among categories treated differently under immigration law. The legal fight therefore concerns a defined group of applicants for admission or adjustment of status, not every immigrant living in New York.

Even with those limits, the lawsuit places Mamdani at the center of a major national immigration dispute less than a year after he took office as New York City’s 112th mayor. Since his January inauguration, he has repeatedly challenged the administration’s use of Immigration and Customs Enforcement while maintaining direct communication with Trump on issues affecting the city.

Asked during the public-charge announcement whether he had discussed the new dispute with the president, Mamdani said he and Trump have “an ongoing conversation around immigration policy.” He acknowledged that the two have deep disagreements involving ICE raids, Temporary Protected Status and public charge, while saying he intends to keep making New York’s case directly to the White House.

That relationship makes the current confrontation more complicated than a simple exchange of hostile statements. Mamdani has publicly described ICE raids as cruel and inhumane and has said the agency should be abolished, yet he has also met and spoken with Trump on housing and other issues where the city believes cooperation is possible. The mayor has presented that approach as one of direct disagreement without cutting off communication.

The public-charge lawsuit now tests how far that dual-track relationship can go. Even while Mamdani says conversations with Trump continue, his administration is asking a federal judge to stop one of the president’s immigration policies before it takes effect. The city is not relying on persuasion alone; it is invoking federal administrative law and asking the court to determine whether DHS stayed within the authority Congress granted it.

The case also arrives amid an intensifying national immigration enforcement campaign. Reuters reported that ICE arrests rose to nearly 51,000 in August, the third consecutive monthly record. Deportations, however, remained comparatively steady at roughly 1,200 per day, with Reuters reporting that legal claims, the lack of existing removal orders for many detainees, transportation limits and restrictions imposed by receiving countries have complicated efforts to convert rising arrests into removals at the same pace.

Reuters also reported that more than three-quarters of recent arrests involved people without criminal convictions or pending criminal charges. That broader enforcement environment is separate from the public-charge rule, which concerns admissibility and adjustment decisions rather than ICE arrest authority. But it helps explain why changes in immigration policy can generate fear well beyond the people directly affected by a particular regulation.

For New York officials, that atmosphere strengthens their argument that vague rules can have consequences before any immigration officer makes a formal decision. The city says families may avoid doctors, food assistance or other programs simply because they do not understand how a future immigration application could be affected. Officials argue that the resulting costs could appear in emergency rooms, homelessness systems, schools and other local services.

DHS takes the opposite view of the policy’s purpose. In the final rule, the department says the 2022 framework constrained officers’ ability to make “accurate, precise, and reliable” determinations and was inconsistent with congressional intent. The administration says officers should be able to consider relevant evidence surrounding an applicant’s financial circumstances rather than being limited by a narrow regulatory definition.
