Indeed, you can have that. All you need to do is to provide proofs that you has been honorably discharged. You can use Form DD-214 from U.S. Department of Defense.
That's great. Is there any charge or fee to pay if i do this?
Not at all. I you apply and were charged a document fee, then you're entitled to a refund for the fee you paid.
This proof i have to submit, it has something to do with it my discharge date?
