Chicago FAQ
Does Chicago require employers to use E-Verify?
No. Neither Illinois nor Chicago imposes an E-Verify mandate on private employers. Federal contractors must enroll under federal rules, but no city ordinance applies.
Can my Chicago employer use E-Verify voluntarily?
Yes. Any Illinois employer may enroll through USCIS but must follow 820 ILCS 55 notice procedures, give workers a chance to contest mismatches, and apply rules consistently.
Oak Park FAQ
Can my Cook County employer require E-Verify?
Voluntarily yes, but they must follow Illinois Right to Privacy in the Workplace Act notice and consent procedures. They cannot use E-Verify to selectively screen workers based on national origin or ethnicity.

Only when federal funds trigger the FAR E-Verify clause. Cook County procurement does not impose a stand-alone E-Verify requirement beyond what federal contracting law requires for the specific funding source.
