Long Island has experienced a steady increase in immigration arrests by U.S. Immigration and Customs Enforcement (ICE) agents amid a broader federal crackdown that has intensified since the beginning of the Trump administration. While much public attention has focused on enforcement efforts in large, densely populated cities governed by Democrats, Long Island’s suburban landscape has seen a sustained and consistent rate of detentions.

Since August, the number of arrests on Long Island has been approximately 60% higher than in New York City or the Hudson Valley, though still slightly below the national average. The region's sprawling roadways and car-dependent communities provide federal agents with greater operational stealth compared to urban centers, where protests and organized resistance often complicate enforcement activities.

ICE agents frequently conduct arrests during traffic stops, taking advantage of the area's less crowded, suburban environment, according to Serena Martin, executive director of New Hour for Women and Children, an advocacy group assisting women and children impacted by incarceration. Martin noted that, unlike in urban areas where demonstrations and rapid mobilizations can quickly gather, residents in suburban settings are less able to document or resist these operations.

In early March, ICE made roughly 12 arrests daily on Long Island, a significant increase from about one arrest per day earlier in the year. Nationwide, arrests also surged, exceeding 1,000 daily in early March compared with approximately 300 daily earlier in 2024.

The political landscape plays a notable role in enforcement patterns in the region. Nassau County, which borders New York City, has a cooperative relationship with ICE facilitated by a Section 287(g) agreement that authorizes local law enforcement officers to assist federal agents in immigration enforcement and detainee transfers. Such agreements have expanded nationwide, increasing from 133 agencies in January 2025 to more than 1,000. Nassau County Executive Bruce Blakeman, a Republican and Trump ally, has strongly endorsed continued cooperation with ICE, arguing it has enhanced local public safety by deporting undocumented immigrants with criminal records.

Critics, including immigrant advocacy groups and local residents, have expressed concern about the impact of these policies. Sandra Valencia of Rural & Migrant Ministry highlighted that ICE agents’ presence near schools has created a climate of fear among students and parents. She also reported instances of intimidation involving children of Republican families displaying American flags at schools.

Additionally, five Long Island residents of Latino descent filed a lawsuit in April alleging that ICE agents have engaged in discriminatory practices by targeting individuals based on their ethnicity rather than immigration status. ICE has not publicly responded to the legal claims.

The enforcement actions have deeply affected families across Long Island, with some undocumented residents preparing emergency plans in case of detention. Others, like 16-year-old Fernanda Mejia, have spoken out at county government meetings, sharing personal accounts of family separations and calling for an end to local cooperation with ICE. Mejia’s father, detained during a search for another individual, reportedly has no criminal record.

During a July public hearing, Nassau County Legislature Presiding Officer Howard Kopel cut short Mejia’s testimony, a move that drew protests from attendees. Kopel declined to comment further when approached for an interview.

While enforcement continues steadily on Long Island, contrasting with the fluctuating arrest rates seen in cities like Chicago and Minneapolis, the debate over local cooperation with federal immigration authorities remains politically charged and deeply personal for many residents.
