N.C. Gen. Stat. § 90-171.32

The Board may, without examination, issue a license to an applicant who is duly licensed as a registered nurse or licensed practical nurse under the laws of another state, territory of the United States, the District of Columbia, or foreign country when that jurisdiction's requirements for licensure as a registered nurse or a licensed practical nurse, as the case may be, are substantially equivalent to or exceed those of the State of North Carolina at the time the applicant was initially licensed, and when, in the Board's opinion, the applicant is competent to practice nursing in this State. The Board may require such applicant to prove competence and qualifications to practice as a registered nurse or licensed practical nurse in North Carolina.
