Moved to nurse registration forum in our world nursing section to elicit further response.
The place to start is the NC Board of Nursing application for license by examination as an internationally educated nurse. The NCLEX is one step in the licensing process. As far as qualifying to work, you need to determine your eligibility for working rights/visa/permanent residence status.
Do you have a valid social security number? NC BoN will not issue a license until you are able to provide a valid social security number.
