The state board of nursing will be where you go to get your license. Once you graduated from nursing school, you took the NCLEX and applied to your nursing board. You are currently working under your state's license.
Unfortunately, the United States hasn't come up with one licensing office. Each state still handles their own and has their own rules.
They are getting closer, though. Some states participate in a nursing licensure compact. If you are lucky enough to live in a compact state, you may not need to apply for a new license.
Until all states participate, though, if you travel, more than likely you will at some point need a new nursing license. The good news is this fee is usually reimbursed by your travel agency.
The bad news is you will need to do a little research. Since all states have their own nursing boards, they each have different paperwork and requirements.
Begin your search by finding the state you will be traveling to.
Once you contact the state board of nursing for the state you are traveling to, they will give you all of the paperwork and information you will need. You may need fingerprints, a physical, proof of vaccinations and other information. Once you have your new license in hand, though, you are ready for your new adventure!
