New York's incoming mayor Zohran Mamdani is assembling a dedicated team to shore up the city's sanctuary laws — a set of policies that have governed how local police and corrections officers interact with federal immigration authorities since the late 1980s.
The Immigration Justice Committee, one of 17 transition committees Mamdani has convened, holds its first meeting this week. Around 400 experts and advocates across all committees are drafting policy recommendations and suggesting appointments for the incoming administration, which has already raised $3 million to fund the transition work.
What sanctuary laws actually do
New York's sanctuary protections specify exactly when the NYPD and Department of Corrections can detain people at the request of ICE (Immigration and Customs Enforcement), and how city agencies can — or cannot — share information with federal immigration authorities. The framework emerged gradually starting in the late 1980s, built on the principle that immigrants shouldn't have to choose between reporting crimes and risking deportation.

Start Your News DetoxAdvocates point to concrete outcomes: these policies help ensure that undocumented New Yorkers can call police about abuse, testify in court, and access city services without automatic exposure to deportation. But the Trump administration has made sanctuary cities a direct target, even suing New York City in July over its policies.
The pressure is mounting
ICE enforcement activity has visibly intensified across New York since Trump returned to the presidency. The New York Immigration Coalition documented a sharp rise in "community arrests" — people detained at home, work, or on the street — throughout the state. Advocates and city council members representing neighborhoods with large immigrant populations report noticing the shift on the ground.
Mamdani's campaign explicitly promised to strengthen these protections, and the committee's composition signals serious intent. The 25 members include leaders from major immigrant advocacy organizations, legal service providers, grassroots groups, religious leaders, and the former commissioner of the Mayor's Office of Immigrant Affairs.
Natalia Aristizabal, associate director of Make the Road NY, said she plans to push two specific priorities: ensuring city agencies actually comply with existing sanctuary laws, and establishing a hotline where residents can report ICE activity. "Once someone calls the hotline, they'd be connected to a rapid response unit that can verify what's happening on the ground," she explained. "It's a structure and resource to track how ICE is operating in those areas. I think it's time New York made this happen."
The committee's work arrives at a moment when sanctuary policies face their sharpest federal challenge in years. Whether these protections hold — and how they might be strengthened — will likely shape how millions of New Yorkers navigate the city over the next four years.
