If you decide that the risk is worth it, and yes it is a risk because regardless of what the BON tells you they will not decide anything until after you graduate, then you need to hire a lawyer. I did. My "charges" (they don't show on a background check) were from five years ago when I was a juvenile and I am being held up. Professors told me that I would probably be okay and that I shouldn't hire a lawyer unless my license got denied, but I knew better as I had done my research.
I hired a lawyer in December, graduated in May, my class mates received their ATT's in July and I still have not heard a word from the BON. It is hard knowing that you went to school for three years, excelled (because I did), yet still may not be granted a license. I knew I was taking a chance but decided to pursue this route anyways because becoming a nurse is what I really want, but you also have to be prepared that they can deny you. And they can deny you, especially with it being a current misdemeanor; they are not necessarily looking at what the charge is, but are going to be looking at the fact that you had a break in morals close to the time when you feel that you can commit to care for the ill and vulnerable.
Regardless of what anyone tells you, hire a lawyer and understand that after going through with school that you may be denied licensure or be placed on stipulations. Do the best that you can in school; put in effort to do so well that you stand out- this will get you reference letters and possibly awards-these things will put some positive light on you when you apply for licensure. I was an amazing student who graduated valedictorian of the nursing class and received an award for it, I had amazing references from all of my professors, the BON (at the start of nursing school) and my nursing professors told me that I should be alright- but I know better and know that I can be denied. Are you willing to take that chance?
