Mayor-elect Zohran Mamdani's transition team is moving quickly on immigration enforcement. This week, the Immigration Justice Committee—one of 17 advisory groups shaping the incoming administration—holds its first meeting to strengthen the city's sanctuary laws, the policies that limit when police can work with federal immigration agents.
The stakes are immediate. Since Trump took office, ICE arrests in New York have surged, with community arrests—people grabbed at home, work, or on the street—now five times more common than arrests made through police collaboration. The Trump administration has already sued New York City over its sanctuary protections, signaling this will be a sustained fight.
What Sanctuary Laws Actually Do
New York's sanctuary framework, built starting in the late 1980s, sets clear boundaries: it specifies when the NYPD and Department of Correction can detain people at ICE's request, and controls how city agencies share information with federal immigration authorities. The logic is straightforward—immigrants who fear deportation won't report crimes, won't cooperate with police, won't seek help. The city loses both public safety and trust.

Last year, the Department of Investigations found that a Department of Correction investigator twice violated sanctuary law by sharing detainee information with Homeland Security agents. These gaps matter when people's safety depends on the rules actually working.
The Hotline Strategy
The 25-member transition committee—led by advocates from Make the Road NY, legal services providers, and faith leaders—is pushing two concrete priorities: ensure every city agency actually follows sanctuary law, and establish a hotline where New Yorkers can report ICE activity in real time.
That second piece is newer territory for New York. California counties and Illinois have built rapid-response networks where people call in ICE sightings, trained volunteers verify what's happening, and legal observers show up to document arrests. The networks don't stop ICE, but they provide witnesses, legal support, and community coordination. Natalia Aristizabal of Make the Road NY sees this as essential infrastructure: "Once you report to the hotline, they connect to a rapid response unit that then is able to verify what's happening on the ground."
The Trump administration opposes these systems—it's criticized them as threats to federal officer safety and recently pressured Apple to remove crowdsourcing apps. But with community arrests accelerating, the argument for real-time coordination is harder to ignore.
The transition committee, funded by $3 million in raised money, has about 400 experts and advocates working across its 17 groups. The Immigration Justice Committee's work this week will shape what New York actually does when federal enforcement intensifies. The question isn't whether ICE will be active—it already is. The question is whether the city's response can keep pace.
