It depends on your state but almost every state (if not every state now) performs a background check prior to approving your STNA. It also depends on your charges (if it is for check fraud, for instance, they might let it go - if it deals with violence you probably won't be approved).
My suggestion is to talk to an attorney. Also, if it's been a while (at least 7 years or so) you should look into expungement of the felony.
