Dui

Has anyone ever heard of someone not receiving their license because of a DUI? I had one back in 1999. It was a horrible mistake and something I regret terribly. Upon registering for the NCLEX the board advised me that my license COULD be withheld due to the conviction. I had to send all the papers clearing me and my police record. I took the test on 3/26 and just got the letter I passed the exam but the board was still investigating my conviction and has not made a decision about giving me a license. I am so bummed! I can't imagine they would not accept me because of one stupid mistake I made many years ago. Any opinions???
