Yes, a registered nurse can work in any state as long as they are licensed in that individual state.
In order to become a registered nurse you must first attend a 2 -4 year nursing program and pass the national licensing exam for registered nurses (NCLEX-RN).
After you’ve acquired your license you may then look for a job and begin practicing in the state you were licensed in.
In order to begin working in another state a registered nurse must first acquire a licence for that particular state.
Note: One confusing thought many individuals have about the NCLEX-RN is that they need to take the exam in each state they apply to work for, however that is not the case since it is a nationally recognized exam it only needs to be taken once.
In order for a registered nurse to get licensed for an individual state they must apply for “licensure by endorsement” for that state, which generally requires a background check, nursing history check and depending on the state the RN applies to he/she may also be required to pass a few addition requirements in order to receive licensure for that state.
The registered nurse must also pay any fees associated with obtaining a license in that state.
Some states have joined what is known as a nurse licensing agreement “nurse licensure compact agreement state (NLC)”, which allows nurses who live and work in compact agreement states to work between those states without the need to obtain licensure for that particular state as long as they maintain their living quarters in the current state they are licensed in.
If the registered nurse decides to move and live in a state that has a nurse license compact agreement he/she will then have to obtain a license for that particular state and go through all of the requirements a registered nurse would have to go through in a non compact agreement state in order to obtain his/her license.
For more information regarding licensing practices and fees you may want to do a search for the local state board of nursing in your state or the state you wish to work in.
