The compact does not cover APRN roles
The Nurse Licensure Compact covers RN and LPN/LVN licenses. It does not cover APRN authorization — NPs, CRNAs, CNSs, and CNMs. That has been the case since the compact began and applies in every state.
What that means in Wyoming
Wyoming is a compact state, so your underlying RN license can be a multistate license. But your APRN authority sits on top of that RN license and is not part of the compact — to practice as an APRN in another state, you generally need that state’s APRN authorization, granted by its board. Confirm specifics with the Wyoming State Board of Nursing.
The separate APRN Compact
A distinct APRN Compact has been drafted to do for advanced practice what the NLC does for RNs and LPNs/LVNs, but it is not yet operational. Until enough states join and it is implemented, APRN privileges do not cross state lines automatically.
