Illinois to Connecticut: journeyman plumber license reciprocity
Illinois does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Connecticut's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Journeyperson (P-2) by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A plumber licensed in any other state applies under DCP's 'Plumbing Journeyperson - Equivalent Out of State License' path. DCP reviews one out-of-state license for equivalency: it must have required the same classroom hours (576 for the P-2), an equivalent classroom curriculum matching Exhibit A, and the same on-the-job training hours (8,000 for the P-2) as the Connecticut class applied for. Limited classes have lower hour tables (J-2 4,000/288, J-4 2,000/144, P-6 2,000/180, P-8 2,000/144). The applicant submits a copy of the license, official license verification, the laws and regulations that set the requirements met to obtain it, and that license's scope of work, with the non-refundable $90 application fee; only one origin license is reviewed. If the license is found equivalent, CGS 20-333 and 20-334a(a)(2) still require the Connecticut journeyperson examination before the $120 initial license is issued—the origin license does not waive the trade exam. If equivalency cannot be proven, DCP will not approve the application on this path (the applicant must instead document apprenticeship or equivalent experience and training). No named reciprocal partners appear on the plumbing out-of-state pages.
The out-of-state page does not itself restate that an exam is required; the exam follows from the scope page ('qualify for this license examination') and CGS 20-333 / 20-334a(a)(2)(A) (unlimited journeyman: apprenticeship of not less than four years and the state licensure examination). Typical processing time is not published.

How Connecticut licenses journeyman plumbers
Connecticut journeyman plumber · “P-2 Unlimited Journeyperson Plumber”
Statewide license
Issued by Connecticut Department of Consumer Protection, Occupational and Professional Licensing
Connecticut licenses plumbers statewide through the Department of Consumer Protection (DCP) under CGS Chapter 393 (plumbing and piping work). The journeyman-level credential is the P-2 Unlimited Journeyperson Plumber, which covers all plumbing and piping work defined in CGS 20-330 while employed by a contractor licensed for that work. Narrower journeyperson classes exist (J-2 well pumps, J-4 lawn sprinkler, P-6 sewer/storm/water, P-8 gasoline tank piping, PP-2 process piping, SP-2 spa and pool). A new P-2 applicant qualifies through a registered apprenticeship, equivalent experience and training, or an equivalent out-of-state license (576 classroom hours matching Exhibit A and 8,000 on-the-job hours) and, under CGS 20-333 and 20-334a(a)(2), must pass the state licensure examination. CGS 20-333a would allow the Commissioner to waive the exam only if the origin state reciprocates for Connecticut licensees; DCP's P-1/P-2 out-of-state pages name no partner states. Application fee $90 (non-refundable) and initial/renewal license fee $120; licenses expire annually (plumbing expiration month not confirmed on the pages retrieved).
Why Illinois has nothing to transfer
Illinois journeyman plumber · “No journeyman tier (Apprentice Plumber is the only sub-licence)”
No individual license at this level
Issued by Illinois Department of Public Health (IDPH), Plumbing Program
Illinois has no journeyman plumber licence. Under the Illinois Plumbing License Law (225 ILCS 320) the Department of Public Health issues a single Plumber licence plus an Apprentice Plumber licence; there is no intermediate journeyman card and no master tier, and the City of Chicago's parallel programme under Section 16 follows the same two-tier structure. Every person who performs plumbing must hold one of those two licences (Section 3(1)). An out-of-state journeyman therefore has nothing to transfer to: the choices are (1) register as an Illinois Apprentice Plumber (age 16 or older, sponsored by an Illinois licensed plumber or an approved apprenticeship programme, maximum six years as an apprentice) and work under supervision, or (2) qualify for the full Illinois Plumber licence, where Section 17(b) lets a plumber licensed by another state with substantially equal requirements sit the Illinois examination without first serving the four-year Illinois apprenticeship. Whether a journeyman-level origin licence counts as 'substantially equal' to the Illinois Plumber licence is decided by the State Board of Plumbing Examiners case by case and is not addressed on the IDPH page reviewed; see the master level for the licence route.
