CHICAGO — Nov. 7, 2025
A third month of stepped-up federal immigration enforcement has left a visible imprint on Chicago and its suburbs, with hundreds arrested, lawsuits multiplying and community unease deepening as the operation known as “Midway Blitz” continues. The scale of arrests, the mix of targeted and incidental detentions, and allegations of unlawful tactics and harsh holding conditions have thrust the region’s long-established immigrant communities into an era of heightened uncertainty.
What the numbers show
Chicago remains a city shaped by immigrants. The foreign-born population reached an estimated 597,415 in 2024 — about 22% of residents — and noncitizens comprise roughly 12% of the city, according to WBEZ. Many have deep roots: more than two-thirds arrived more than 15 years ago, the station’s analysis notes. “Immigrants are still arriving in Chicago and we’re pulling our weight with respect to helping the city of Chicago grow its population,” said Fred Tsao, senior policy counsel at the Illinois Coalition for Immigrant and Refugee Rights (ICIRR).

Unauthorized residents are a significant share of that landscape. County-level estimates indicate roughly 369,000 unauthorized immigrants live in Cook County, with about 487,000 statewide in Illinois, data show from the Migration Policy Institute. In Cook County, a large portion are of Mexican or Central American origin, and many have lived in the United States for a decade or longer, reflecting strong community and labor-market ties, according to the institute.
Those contemporary figures arrive after a period of decline: between 2007 and 2017, Chicago lost nearly 31,000 immigrants, a drop that raised alarms about long-term economic and workforce impacts in sectors reliant on immigrant labor, analysis by the Metro Planning Council found.
Enforcement scale and how arrests are being made
Federal officials launched “Operation Midway Blitz” in early September, and arrests piled up quickly. From Sept. 8 to Sept. 19, immigration authorities arrested nearly 550 people in the Chicago area, reporting shows from the Associated Press. About 50% to 60% of those taken into custody were targeted because of criminal histories or final removal orders, while the remainder were people encountered incidentally during raids, the AP reported. The distinction has not eased anxiety in affected neighborhoods; coverage has highlighted misidentification concerns and broad fear among immigrant families, according to the Associated Press.
In court, advocates are also challenging how arrests are conducted. A legal filing alleges immigration agents carried out multiple warrantless arrests in suburbs including Woodridge, Palatine, Arlington Heights, Naperville, Mount Prospect, Berwyn, Elgin and Cicero, despite a settlement requiring warrants or reasonable suspicion before such detentions, according to WBEZ. The filing frames the incidents as violations of legal protections against warrantless arrests and seeks judicial intervention, the station reported.
Legal challenges and facility conditions
The scrutiny extends inside detention. Advocates filed a lawsuit alleging the ICE facility in suburban Broadview has denied detainees private legal phone calls; blocked access for members of Congress, journalists and religious leaders; coerced detainees into signing incomprehensible documents; and deprived people of medical care, basic necessities and adequate food, according to The Guardian. “People are being kidnapped off the streets, packed in hold cells, denied food, medical care, and basic necessities, and forced to sign away their legal rights,” said Alexa Van Brunt, the director of the MacArthur Justice Center’s Illinois office and lead attorney for the lawsuit.

The lawsuit’s claims underscore a wider legal and political clash over enforcement tactics and detention standards, even as day-to-day operations continue. Together with the allegations of warrantless arrests in multiple suburbs, the suits paint a picture of an enforcement campaign increasingly fought in courtrooms as well as on city streets, according to WBEZ and The Guardian.
What residents face now
The combined effect of large-scale operations and legal uncertainty has weighed on daily life in immigrant neighborhoods, with families adjusting routines amid the fear of incidental encounters, reporting shows from the Associated Press. Community organizations and attorneys have stepped up legal challenges and public information efforts, a response shaped by the region’s sizable immigrant population and the deep roots many residents have established over decades, according to WBEZ and the Migration Policy Institute.
As enforcement continues, the stakes for Chicago are unusually high. The city’s immigrant communities are both numerous and longstanding, a demographic reality intertwined with the regional economy and workforce, the Metro Planning Council has noted. With arrests mounting and lawsuits pressing claims from street-level detentions to detention-center conditions, the next phase of “Midway Blitz” will likely be shaped as much by court rulings and policy debates as by operations on the ground — and watched closely by a city where immigrants are central to its past and its future, according to WBEZ and the Associated Press.
