Immigration enforcement operations in the Chicago area have shifted to target courthouses and routine immigration check-ins, according to immigrant attorneys and advocates. Enforcement appears to focus on immigrants who entered through Biden-era parole programs and those with pending cases or unresolved charges. The trend has complicated decisions for immigrants seeking to comply with legal proceedings; attorneys warn that courthouse arrests undermine due process protections. Advocates express concern that many people being detained while attending hearings or check-ins have not been convicted of crimes or have pending cases still unresolved.
