Illinois has no E-Verify mandate for private employers and actually restricts mandatory enrollment under the Right to Privacy in the Workplace Act. Cook County imposes no additional E-Verify requirement.
Federal law requires E-Verify only for federal contractors and certain federally funded employers. Illinois state law (Right to Privacy in the Workplace Act, 820 ILCS 55) regulates private employer E-Verify use, requiring posted notices, employee consent procedures, and prohibiting use of E-Verify to discriminate. Illinois explicitly does not mandate E-Verify for private employers. Cook County imposes no county-level E-Verify requirement on businesses, contractors, or employers operating in unincorporated areas or suburbs. The county does require its own contractors to comply with applicable federal E-Verify rules where federal funding triggers the mandate. The overall posture is permissive, prioritizing worker-privacy protections over employer-side immigration verification mandates.
Illinois employers misusing E-Verify face Department of Labor fines up to $500 per first violation, $1,000 for repeat. Cook County does not enforce additional E-Verify penalties on private businesses.
