I know for the state of Texas you will have to jump through hoops to get your license, if they'll even let you get it, and some schools won't even touch you if you have one. If this is your first DUI, learn the lesson this gave you, pay a lawyer the $5K or so to clear it up and never do it again. This may have killed your chances of getting into a school and/or allowing you to sit for the exams. Don't wait too long to find a lawyer, there should be plenty that specialize in DUI's unless you live in a small town. We had to submit for a background check before we were allowed to sit for our first day of class and I'm sure this is one of the things they check. Also, after your first year when you apply for your intern license through your state board, they will check both state records as well as do a FBI check.
Why would a school waste a spot on a student that might have problems getting licensed when they could give that spot to someone that would become a pharmacist?
