I entered the US on a B2 visa. Then overstayed for a period of over 8 years. I left the country voluntarily and became a citizen of an European country. I attempted re entry in the US with my newly acquired passport and without a visa (Visa waiver), and was allowed for a period of 90 days. I stayed only for 5 days and then came back to Europe. I'm seeking a carrier on the tourism business, and I'll need to travel a lot between the US and Europe,but for what I've understood in order to travel back and forth the US repeatedly I will need a visa and not just a visa waiver. Question is, when I file my petition for a visa will I be asked about my previous citizenship and whatever I did when I was only a citizen of that country? The fact that I entered in the US with my new passport demonstrates that since I've never overstayed on a visa waiver I'm eligible to use it, but I'm still banned to get a visa since I previously overstayed. Will I lose my visa waiver privilege if a visa is denied?
