Verdict
Full re-application
Illinois has no plumbing reciprocity or endorsement covering North Carolina, so this is a full journeyman application either way. Illinois requires every out-of-state plumber to pass the Illinois plumber's licensing examination; the application's out-of-state section accepts prior apprenticeship/licensure toward the four-year experience prerequisite but does not waive the exam. The only license-WITHOUT-examination pathway is for a holder of a current City of Chicago plumber's license (an intra-Illinois municipal reciprocity), not for licensees of other states. The productive plan: gather proof of the apprenticeship or on-the-job hours you logged in North Carolina, register for Illinois's journeyman exam, and treat your experience as exam preparation and as credit toward Illinois's experience requirement. Budget a new-applicant timeline and order your certified license history early — it is the long-lead item.
