Federal immigration agents arrested 352 people on Long Island in January, the highest monthly total recorded in data tracking enforcement between last fall and early March, according to figures from the Deportation Data Project.
That works out to roughly 11 arrests per day. For context, that’s a pace that would fill a small school in a month.
The numbers come from arrests recorded in Nassau and Suffolk counties, the Nassau County jail, and a processing facility in Central Islip. They don’t capture the full human count so much as they trace a pattern, and the pattern is unmistakable: Long Island has become one of the most intensively policed immigration corridors in the northeast.
February brought some relief. Arrests dropped to 223 as federal agents were pulled away following unrest in Minnesota connected to enforcement actions that killed two U.S. citizens. A dip, not a halt.
Then March came back hard. In just the first 10 days, agents made 118 arrests on Long Island. Sustained at that rate, the month could approach or match January’s record. Full March data hasn’t been released yet.
The thing is, Long Island isn’t proportionally a high-density target if you go by population. The Migration Policy Institute estimates roughly 15% of New York State’s unauthorized immigrants live here. But since last fall, more than half of all ICE arrests in the broader New York City region, which includes the five boroughs and surrounding counties, have happened on Long Island. That’s a massive overrepresentation, and immigration advocates say it signals a deliberate concentration of enforcement resources here rather than any organic reflection of where people actually live.
Most of those arrested were men in their 30s from Central American countries, primarily El Salvador and Honduras. But the data also shows at least 17 children detained since the crackdown began, some as young as 5 years old. That number deserves to sit on the page for a moment without editorial padding around it.
In Nassau County, 144 of the January arrests were tied to a local agreement with U.S. Immigration and Customs Enforcement that lets the agency use the county jail in East Meadow for detention and coordinate directly with local law enforcement. That arrangement has drawn scrutiny from immigration advocates, who argue it makes Nassau a logistical hub for regional enforcement in ways that go beyond passive cooperation.
Immigration advocates describe the overall trend as a sharp escalation under President Donald Trump. They also note a rise in the number of detainees choosing to contest their cases in court, which suggests that at least some of those swept up believe they have legal ground to stand on. Whether the courts can process that volume fast enough is a separate question, and not a simple one.
I’ve been covering Long Island from up here near Cooperstown long enough to know that immigration enforcement in Nassau and Suffolk has always had its own political weather. The history here goes back decades: the federal crackdowns after the 1990s gang violence, the post-2007 hate crime spike in Farmingdale and Patchogue, the fights over day laborer centers in towns like Oyster Bay. Local officials have cycled through cooperation and resistance with federal immigration priorities depending on who’s in office and what year the election falls.
What’s different now is the scale and speed. Three hundred and fifty-two arrests in a single month. Eleven per day. Children as young as 5.
The data was analyzed and first reported by the Long Island Press, which reviewed newly released federal records detailing regional enforcement trends.
Nassau County’s arrangement with ICE isn’t new, but its implications look different when the arrest numbers are this high. The East Meadow jail isn’t a facility built for long-term immigration detention. Using it as a regional processing hub while arrests run at record pace raises infrastructure questions that local officials haven’t fully answered publicly.
Suffolk County’s position in the data is notable too. Both counties together account for an outsize share of a national enforcement surge, and Long Islanders paying attention to school budgets and property tax rates may not realize their county governments are also playing a direct operational role in federal immigration machinery.
The full March numbers will tell us whether January was a ceiling or a floor. Based on the first 10 days, there’s no reason to assume the pace has slowed.
