Thanks for the chance to help. I am an attorney with over 12 years military law
What you describe is an "NCIC" record.
The NCIC is the National Criminal Information Center". This is a database maintained by the FBI and contains records of criminal activity, including arrests, warrants, and adjudication of criminal cases.
The data will not expire...it remains in the NCIC indefinitely. There is no way to "expunge" a record that is accurate.
Now...if the record is inaccurate, you can ask to have it corrected.
For example, if the record incorrectly listed the offense for which you were cited? You can request to the agency that made the entry to have them correct it. If they refused, and you could prove it was in error, you could sue them in federal court to force a change.
But there is not a way to force removal of the record if it is otherwise accurate
Sorry to have to bear bad news.
Let me know if you have more questions...happy to assist if I can
