Hello and thank you for your question.
What you will need to do, is see a psychiatrist or psychologist, or therapist in your area who can do an assessment on you, and then submit a report stating that your ADHD is resolved. Do you feel like you still have this condition? Did you get treatment for the ADHD when you were released?
Also which part of the country do you live in, and I can help you to find a clinician to assess you.
Okay I see what you are saying. Then you shouldn't have any trouble at all getting a psychiatrist or therapist to do an assessment that says you are okay.
The cost will vary but it should be something you can afford... and you can also always go to the counseling center at your college too, and they would provide free to very low cost for this service.
Also, here are four therapists in your area (utica) who could also do this for you. It should not have to take long to have this done, or be costly, as you really don't have any history of mental health problems, etc. Please click green ACCEPT button for this information, so I'm credited for my help today.
