This appears to be TX's expunction law. It appears you could not even get a TX conviction expunged from your "individual" facts.

AZ does not have an expunction law, according to this site:
...Can I get my record expunged?
Arizona law does not have an expungement provision. Charges for any type of crime will remain on your record until you reach age 99.

My state though will expunge a federal conviction, certain ones of course, for INTRAstate purposes, assuming of course certain facts weigh in, such as it is a 1st offense, time frame from crime, etc., etc.
