Is a Connecticut Resident Permit Valid in Illinois?

Why

• Illinois does not recognize any out-of-state carry permit.

ISP (official 2025 brochure): 'Illinois does not recognize concealed carry licenses from other states.' Sole carve-out: a resident of another state with a valid concealed carry license from their home state may carry a concealed firearm within a vehicle while traveling through Illinois; if the vehicle is left unattended the firearm must be stored in a locked vehicle or locked container out of plain view (430 ILCS 66).

Carry rules in Illinois

Carry law is state law. From the moment you enter Illinois, these rules replace the ones you know from Connecticut.

• Disclosure is on-demand only: upon an officer's request during a stop, the licensee or qualifying non-resident must disclose that they possess a concealed firearm, present the license on request, identify the firearm's location, and permit the officer to secure it for the stop (ISP brochure, per the Concealed Carry Act).
• Illinois limits magazine capacity to 15 rounds — a limit that applies to visitors, and one of the easiest laws to break by accident.
• Illinois is not a permitless-carry state: concealed carry there requires a permit Illinois recognizes.
• Illinois CCL holders may carry loaded and concealed in a vehicle; non-residents with a valid home-state license may carry loaded/concealed only within a vehicle; everyone else must transport firearms unloaded and enclosed in a case (or broken down / not immediately accessible).

Frequently asked questions

Does Illinois honor a Connecticut non-resident permit?

Not recognized. The answer is the same as for the resident permit on this page.

Can an Illinois resident permit holder carry in Connecticut?

Not recognized. Reciprocity is decided by the destination state, so the answer in this direction depends on Connecticut's law, not Illinois's.

Where does Illinois publish its official reciprocity list?

Illinois publishes its recognition policy on an official state page, linked in the sources on this page. That page is the authority — check it shortly before travel, because recognition lists change without much notice.
