I was pulled over driving a semi truck without having an authorization to work in the states four years ago. They detained me for 2 weeks until I posted a bond. Immigration case was opened because I overstayed my J1 visa for more than a year. Immigration Judge granted me voluntary departure and I left the country right away. From my home country I sent a request for a FBI criminal background check and got the letter with no criminal records but a statement that I was 'Deportable alien' . Since I was granted a voluntary departure, does it mean that my case was dismissed? If so, Is there a way to expunge this record? Any advise would be appreciated.
