You need an immigration attorney. People have been deported due to crimes committed when they were juveniles.

The doctor above was being deported DUE TO MISDEMEANORS he had when he was 17. Yours would be a felony. I would worry more about being allowed to remain in this country rather than becoming a citizen.
