If the theft was your first offense, you may have been part of a diversionary program. That means that if you paid your fine and completed any terms of probation, at the end of the term, the case would be dismissed.
Even if the case was dismissed, it doesn't mean that law enforcement is not entitled to have a copy of your fingerprints. Actually, that probably should have been done at the time you were arrested. However, if the case was dismissed, you may be able to seek permission of the court in which you were sentenced to not have your fingerprints taken because the case was dismissed. If your fingerprints do have to be taken and the case has been dismissed, you may ask to have any fingerprint card destroyed.
As far as your FBI clearances, chances are that the charge segment of theft would show up, even if the case was dismissed. If it was dismissed, this means that there was no conviction and the FBI may not be concerned.
You should contact an attorney who specializes in criminal law. You can contact your local bar association for a referral. It will probably give you 2 or 3 names. You can contact the attorney(s) for a telephone consultation, or ask to set up an appointment to discuss the specific facts of your case. Sometimes, these consultations are free.
