Hello, how can I sign up for a license for New Jersey if I already have a Pennsylvania license?

Apply for a license in New Jersey by endorsement New Jersey will use your NCLEX from PA. Hope it helps.

If you have a license from a compact state you can use it to work in another compact state- you don't have to obtain a NJ license. If you move to NJ and that is your perm. state of residence then you would apply for a NJ multi-state license with your NJ address and that would be your new license.

Pennsylvania and New Jersey both participate in the Nurse Licensure Compact. I am not sure how to do that thru NJ from Pa. The NJ BON website may be a good place for more information. https://www.njconsumeraffairs.gov/nur/pages/applications.aspx
Good luck!
