Approval to take NCLEX and practice as a GN in Texas

Hello,

let me start off by saying i have no criminal history. I did receive an entry level seperation from the army a couple years ago. There was no corrective action, just a problem that happened at the processing center. Before starting nursing school, i sent in a declarly order to texas bon and showed them my paper and explained what happened just to be on the safe side. A week later i got a letter stating i was approved to sit for the NCLEX and practice as a GN after finishing school. My question is: can the board allow you to sit for your nclex but then deny you a license if you still have remained with no criminal history? I have read some horror stories about boards allowing people to take the nclex but then they deny them a license after they pass? Why would any board do that? Am i just being paranoid? Thank you for any imput.
