Thank you for the information and your question and I am sorry to read about your situation. Unfortunately, despite what information might be floating around on the internet the Boards (Discharge Review and Board for Corrections of Military Records-depending on how long ago someone was discharge) do not have the authority, nor will they, upgrade a discharge or change an RE code, etc., for anything other than a legal error or an "injustice." The fact that someone made a one time error in judgment or that they have lived a spotless and stellar life after service, has no bearing on whether an change in their discharge record can be made.
So, unless you have evidence of the error or injustice I mentioned, there wouldn't generally be any pay off in filing for a change. You certainly have the right to try though. You can find out how to do so by going to Board sites to see which Board you would apply to. Here are their links:
Please feel free to ask for clarification if needed. However, I will be out of pocket starting in 2 hours for up to 6 days and will have to get back to you after I return. If you do not need any further information, then if you could take a moment to leave a positive rating in the ratings box above of my efforts to assist you, then Site will then give me credit for assisting you. Thank you
