I will be graduating with an Associates Degree in Nursing this month and plan to take the NCLEX exam in July.
I don't think it's necessarily relevant that the OUI happened in a state other than that where you want to get licensed as an RN. I would check with the state of NH regarding obtaining an RN license with a DUI (or OUI) conviction on your record. I would expect that this information would be available online. Good luck.
