On January 10, 2025, Mayor Brandon Johnson's administration in Chicago reaffirmed its commitment to the Welcoming City Ordinance, which is in accordance with the Illinois Trust Act. This reaffirmation signals the city's dedication to maintaining a welcoming environment, especially amid expected shifts in federal immigration policies. The administration has issued comprehensive guidelines specifically addressing visits from U. S. Immigration and Customs Enforcement (ICE), instructing city officials on how to respond effectively.

Key recommendations include contacting designated legal counsel, ensuring that ICE officers present proper identification, and meticulously documenting all interactions during ICE visits. Additionally, the guidelines extend to other federal representatives and non-federal representatives, emphasizing the importance of deferring to law enforcement in cases of criminal behavior. This initiative reflects Chicago's broader strategy to uphold the rights of undocumented immigrants while aligning with federal regulations. The guidelines are subject to revision, indicating the administration's adaptability to changing circumstances. Overall, this move reinforces Chicago's stance as a sanctuary city committed to inclusivity and protection for all its residents.
