September 14, 2026 NEW YORK, NY In a high-stakes legal showdown with massive national implications, New York City Mayor Zohran Mamdani announced a major multi-city lawsuit targeting the Trump administration’s aggressive attempt to reshape the nation's green card rules.
Filed on September 14 in Manhattan federal court, the 108-page complaint demands that a judge immediately strike down and block a sweeping new "public charge" policy set to take effect on Friday, September 18. New York City stands at the head of a heavyweight coalition including Chicago, San Francisco, Seattle, Washington D.C., and Santa Clara County. New York Attorney General Letitia James is heading a parallel legal attack on the measure.
At the heart of the fight is a radical shift in how federal immigration officers evaluate potential permanent residents. Historically, a "public charge" designation was reserved for individuals primarily reliant on the government for basic subsistence, such as long-term institutional care or direct cash welfare.
The administration’s updated guidance dramatically widens that net. Starting September 18, U.S. Citizenship and Immigration Services (USCIS) officers will be empowered to scrutinize "any and all" means-tested public benefits as part of an applicant's evaluation. This includes essential safety-net programs such as food stamps, housing subsidies, college financial assistance, and potentially even WIC benefits for mothers and infants.
Federal officials defend the policy, arguing it upholds congressional intent by ensuring immigrants arriving in the United States remain self-sufficient rather than relying on taxpayer-funded programs.
City leaders, however, contend the rule flies in the face of established law, bypassing standard procedural requirements while imposing severe, unlawful conditions on immigrant communities.
"The new public charge rule seeks to push immigrant families away from the programs that have kept people fed and healthy for decades," Mayor Mamdani said in a statement highlighting the far-reaching economic and public health fallout. "New Yorkers will be afraid to see a doctor or ask for help they are legally entitled to. Families who remain fully eligible for benefits will feel a chilling effect, and all New Yorkers will pay for it."
The stakes for the nation's largest metropolis could not be higher. More than 3.1 million New York City residents—roughly 38% of the local population—are foreign-born, and fully half of the city's children live in households with at least one immigrant parent.
