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 Guam
Guam has partial compact implementation: an out-of-state multistate license may be recognized for RN and LPN/LVN practice, but Guam residents generally cannot yet obtain a Guam-issued multistate license. Either way, APRN authority is separate from the compact — to practice as an APRN in Guam, you work through the Guam Board of Nurse Examiners; to practice as an APRN elsewhere, you use that state’s process.
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.
