Key Takeaways
• The Chicago Police Department strengthens its sanctuary policies with a memo limiting federal immigration cooperation.
• Aldermen propose amending the Welcoming City Ordinance to allow cooperation in cases involving serious crimes.
• Federal operations and legal threats escalate tensions with Chicago’s sanctuary city stance.
The Chicago Police Department (CPD) is currently facing questions after reports indicated that officers were instructed to inform federal authorities about arrests involving migrants. This situation is particularly delicate as Chicago reaffirms its status as a sanctuary city, a designation rooted in its long-standing Welcoming City Ordinance. This unexpected development has prompted fierce discussions on the city’s commitment to protecting immigrant communities and its approach toward federal enforcement.
Sanctuary Cities and Chicago’s Welcoming City Ordinance

Chicago 🇺🇸 has long stood as a sanctuary city, a stance that seeks to protect undocumented immigrants by limiting collaboration between local law enforcement and federal immigration agencies. Anchoring its efforts is the Welcoming City Ordinance, which forbids city agencies, including the CPD, from cooperating with federal authorities solely on immigration matters. This ordinance ensures that immigrants—whether documented or not—can use local services, report crimes, or seek help without fear of deportation.
The fundamental goal of the sanctuary city model is to build trust between marginalized communities and local governments. Without such trust, immigrants may avoid seeking police assistance or accessing health and social services for fear of encountering immigration enforcement. However, this model has attracted criticism, with opponents arguing that sanctuary policies could hinder public safety by limiting federal law enforcement’s ability to address individuals posing threats.
The Memo That Sparked Controversy
In September 2024, internal directives within the CPD seemingly reinforced the city’s sanctuary principles. A leaked memo instructed officers not to support Department of Homeland Security (DHS) agents during immigration arrests. Officers were told to consult their supervisors and possibly step away from such situations unless expressly directed otherwise. This decision echoed Mayor Brandon Johnson’s administration’s unwavering support for sanctuary policies.
Nevertheless, the memo raised eyebrows, particularly as federal immigration policies under President Biden continued to evolve through 2024. The CPD confirmed the authenticity of the memo but refrained from disclosing whether its guidelines came directly from the Mayor’s office. Many saw this as Chicago drawing a line against increasing federal enforcement activities targeting urban immigrant communities.
Welcoming City Ordinance Faces a Challenge
Just as the CPD reaffirmed its commitment to sanctuary practices, Chicago’s Welcoming City Ordinance faced a significant challenge in January 2025. Aldermen Raymond Lopez and Silvana Tabares introduced a proposal to amend the ordinance. They aimed to loosen restrictions by allowing CPD officers to work with federal agencies when arresting or prosecuting individuals involved in specific crimes, such as drug trafficking, gang-related activities, prostitution, or sexual offenses involving minors.
This amendment ignited sharp debates. Supporters argued that the proposed amendment would bolster public safety by ensuring people involved in serious crimes would not evade federal law. They framed it as a necessary compromise between Chicago’s sanctuary stance and its responsibility to protect its residents from individuals who jeopardize public welfare.
Opponents warned of the deeply harmful consequences the amendment could have on immigrant communities. Immigration advocates, along with several residents, expressed concerns that cooperation with federal agencies—even in limited cases—would erode trust. They questioned how any immigrant could feel safe interacting with the CPD if officers might share information with immigration authorities in certain situations. Critics also pointed to Illinois’ TRUST Act, which limits local law enforcement agencies from partnering with federal immigration officials, as evidence that the amendment conflicted with state law.
Mayor Brandon Johnson responded decisively, rejecting the proposed amendment outright. Johnson emphasized that public safety should not be built on fear or the risk of deportation for residents. His administration made it clear that maintaining the Welcoming City Ordinance in its current form was essential for preserving the sanctuary promises made to Chicagoans.
Complications from Federal Enforcement
This local debate is playing out against a backdrop of increased federal enforcement efforts. In early 2025, U.S. Immigration and Customs Enforcement (ICE) launched operations in Chicago targeting individuals they classified as “known criminals.” These raids underscored the glaring conflict between federal priorities and Chicago’s sanctuary stance. As a sanctuary city, Chicago does not enforce immigration policies at the local level, but ICE operations bypass city involvement, creating tension on the ground.
Federal actions grew even more pressing in February 2025 when the Justice Department escalated its stance. Federal prosecutors were instructed to pursue legal action against state and local officials believed to obstruct federal immigration laws. According to some interpretations, this effort by the Department of Justice was a direct response to cities like Chicago where sanctuary policies limit the scope of federal immigration enforcement.
For municipal leaders and immigrant communities, these heightened federal efforts sowed uncertainty. Officials worried that repeated threats of federal intervention could strain already limited city resources. For immigrant families, the presence of ICE operations in their neighborhoods has contributed to a climate of fear, with many individuals avoiding public spaces or even foregoing essential services to avoid potential encounters with law enforcement.
Conflicting Views Within the CPD
Navigating this tense environment has also revealed divisions within the Chicago Police Department. Some officers view sanctuary policies and directives like the September memo as hindrances to their work, particularly during situations involving federal immigration operations where their involvement is legally complicated.
A source from the department, describing their feelings as “sickening,” expressed concerns that such policies could harm officer safety or contribute to broader public risks. The source highlighted the operational challenges of state-based sanctuary policies intersecting with aggressive federal campaigns.
On the other hand, many officers understand and support the rationale behind Chicago’s stance. Building trust with immigrant communities is seen as key to effective community policing. In neighborhoods with large immigrant populations, fostering cooperation with residents has helped the CPD solve crimes, prevent violence, and protect vulnerable groups. Sanctuary policies facilitate those goals by creating an environment where immigrants feel safe reaching out to law enforcement.
Broader Implications for Immigrant Communities
For immigrant communities, sanctuary city protections are reassuring, but they don’t erase the looming anxiety that federal actions create. Families often find themselves living in fear as legal confrontations between city, state, and federal authorities continue. Although the city’s policies provide a framework of protection, immigrants know federal enforcements can intervene at any time, placing their safety and livelihoods at risk.
Advocates emphasize that sanctuary policies aren’t merely symbolic but have real-world implications for family unity, community health, and broader societal wellbeing. Conversely, opponents continue to argue that such policies hinder the ability of law enforcement to address serious threats.
What Lies Ahead?
The dynamic between local sanctuary policies and federal enforcement shows no signs of resolution in the immediate future. For Chicago 🇺🇸, the Welcoming City Ordinance has become a symbol of its dedication to immigrant protection, but maintaining this status likely means facing continued federal scrutiny.
Future developments could set critical examples for other U.S. cities. Any legal challenges to Chicago’s policies will influence how sanctuary cities navigate their relationships with federal authorities. Additionally, increased federal incursions—whether through arrests, litigation, or funding threats—are poised to keep tensions high.
The importance of compromise and collaboration cannot be overstated. Chicago leadership will face mounting pressure to address public safety concerns while remaining committed to protecting immigrant communities. Similarly, federal policymakers may need to reconsider how their directives affect cities striving to balance safety with inclusivity.
Despite these uncertainties, Chicago remains resolute in its commitment to being a sanctuary city. As a leading example of urban sanctuary policies, its ongoing struggles illustrate the challenges and complexities cities face when tasked with protecting their immigrant populations amidst changing national landscapes.
