The following cities are reportedly expected ICE deportation operations starting Tuesday and continuing into next week, per ABC: Chicago, Washington, D.C., area, Philadelphia, Los Angeles, and Denver

“They feel targeted for who they are, reliving the fears they had eight years ago,” said Sanchez of St. Rita of Cascia Parish on Chicago's South Side. “There’s a sense of unease, like this city is no longer their own because of the looming threat.”

Sanchez, whose congregation has been predominantly of Mexican descent since the 1980s, dedicated Sunday Mass to showing “solidarity with our immigrant brothers and sisters.”

Some undocumented immigrants are taking precautionary steps, such as granting power of attorney to trusted individuals, arranging childcare in case of family separations, and installing security cameras at their homes in anticipation of potential immigration enforcement actions. Others, heeding advice from Trump aides, have left the country voluntarily.

While plans for deportation raids remain fluid, federal immigration officers are expected to focus on more than 300 individuals with records of serious, violent crimes, according to an official who spoke on condition of anonymity because the plans have not been publicly disclosed.

The operation is set to begin in the Chicago area and continue throughout the week, though severe weather may cause delays. Temperatures in Chicago have plunged to 6°F (-14.4°C), with cold conditions forecasted to persist.

Historically, U.S. Immigration and Customs Enforcement (ICE) arrests only a fraction of its intended targets during such operations. However, Trump is anticipated to expand enforcement efforts compared to President Joe Biden. Under Biden, arrests focused primarily on individuals with serious criminal backgrounds or national security risks, and mass worksite raids — common during Trump’s previous term — were halted.

Trump aides have indicated that others, such as spouses or roommates who are undocumented but not primary targets, may also be detained during these operations.

On Saturday, Trump reiterated to NBC News that mass deportations remain a high priority, though he did not specify when or where they would begin. “It’ll start very early and move quickly,” he said, adding, “I can’t name the cities yet because things are evolving. But you’ll see it happen firsthand.”

Sanctuary cities, which restrict local law enforcement from cooperating with federal immigration agencies, have been a frequent target of Trump’s rhetoric — particularly Chicago.

Chicago, the nation’s third-largest city, has been a sanctuary city since the 1980s, with policies strengthened over the years, especially following Trump’s inauguration in 2017. Just last week, the Chicago City Council overwhelmingly rejected a proposal that would have allowed police to collaborate with ICE on deportation cases involving criminal accusations or convictions.

Tom Homan, Trump’s incoming “border czar,” criticized Illinois’ Democratic leaders during a recent visit to the Chicago area, hinting that enforcement efforts would focus there. However, in recent days, he acknowledged that plans are still evolving.
