Before You Become a Travel Nurse in Different States read this 

There isn't one specific degree you need to become a travel nurse – you can be a travel nurse with an Associate Degree in Nursing (ADN) or a Bachelor of Science in Nursing (BSN). However, many agencies prefer candidates with a four-year degree, so a BSN might make it easier to get hired by an agency and find the jobs you want.

Travel Nurse License Requirements

All registered nurses must be licensed in the state where they practice. But things can be a bit trickier when it comes to travel nurse license requirements.

As a travel nurse, you'll apply for licensure in the state where you maintain your permanent residence. In many cases, you won't need to apply for separate licensure even if you go out of state on a travel nurse assignment. That's because of the Nurse Licensure Compact (NLC), an agreement that allows licensed RNs to practice legally in other participating states. Currently, 39 states participate in, or are in the process of implementing the NLC.
