Hello again Kenneth,
My name isXXXXX'm a licensed attorney. Glad to try and help out.
Sure sorry for the circumstances, truly. My heart goes out to you.
I will speak candidly rather than doing you the disservice of lying or misleading you. I didn't enact the law, and personally I often disagree with it, but nevertheless we're all stuck with it. I just wouldn't do you the disservice of lying or misleading you. So, here's the truth.
You do not qualify for expungement of a federal conviction, pursuant to 18 USC § 3607. Unlike most states, federal law does not operate this way. I would love to say otherwise, but that would be a lie.
I am sorry.
However, you do qualify to apply for a Presidential Pardon:
United States Department of Justice
If you have a follow-up question or need clarification, please just say the word by using "reply" to reach me.
I truly hope all works out for you.
