In order to take an assignment through Nomad, you need to be licensed to work as a nurse in the state where your assignment is located for the entire duration of your employment. This doesn’t necessarily mean that you can’t apply for a job in a state where you don’t already have a license. As long as the required license is active by the time your assignment starts, you can definitely apply to the job with the note that you are “willing to obtain” the proper licensure.
Since each state has a different estimated turnaround time for obtaining a license, we recommend that you reach out to that particular state’s Board of Nursing. You may view approximate timelines for obtaining a license in each state here.
