For Nurse Licensure Compact purposes, primary state of residence, or PSOR, is the nurse's legal home state. A nurse has one PSOR. Owning a house in a state does not establish it, and the address of the next assignment does not automatically replace it.
The compact identifies documents such as a driver's license, voter registration and federal tax filing as evidence of legal residence. The board's application instructions specify the documentation it will accept. Treat the declaration as a legal fact to establish, not an option to choose according to which state processes licenses fastest.
Two assignments that look similar
Consider two nurses renting apartments near the same hospital.
The first is on a temporary assignment and continues to maintain legal residence in the home state. The compact's residency guidance distinguishes that situation from a permanent relocation. The length of the contract alone does not establish a change in PSOR.
The second has moved with the intention of making the destination the new legal home. A short initial employment contract does not necessarily make that residence temporary. The relevant facts include the move and the intention to establish the new primary residence.
The compact's own examples also address a travel nurse who later decides to remain permanently. A temporary arrangement can become a relocation; the original assignment label does not settle the question forever.
What the 60-day rule requires
Under Rule 402(2), a multistate licensee who changes PSOR from one compact state to another must apply for a multistate license in the new home state within 60 days.
That is an application deadline. It is not a requirement that the board finish processing and issue the license within 60 days. The compact's published FAQ makes this distinction explicit.
For a compact-to-compact move, also check the former license's expiration date. The transition guidance describes practice under the former home-state multistate license until the new one is issued, but an expiring former license can interrupt that sequence. Do not build a relocation plan around an assumed automatic extension.
Build a relocation record
Before moving, collect the new board's endorsement instructions, required residence evidence and the current license's expiration date. Record when the legal relocation occurs and retain the application confirmation.
If plans change during a travel assignment, revisit the residence question. Ask the relevant board how the documented facts affect the license and deadline. Give dates and circumstances rather than asking only whether a “travel nurse” needs another license.
Notify the former board through its required process. Once the new home state issues the multistate license, the former one is deactivated under the compact's moving guidance.
Use the correct moving scenario
Moving to a noncompact state follows a different route: the former multistate license becomes single-state, and authorization in the destination must be addressed separately. See single-state and multistate licenses.
Military-family and federal-employment circumstances can require additional analysis. Do not use an ordinary travel-assignment example to resolve those situations. The aim is a documented licensing answer that matches the nurse's actual legal residence and work.
