I Recently came back from Greece where I met my family for the first time. I am interested in getting dual citizenship for USA/Greece but I don't know where I can get information. Does anyone know of a website or place that I can contact to get more information?

You need to find out who your closest direct ancestor [preferably on the patrilineal side] was registered in Greece as a citizen. If it was your father, then it should be quite easy. If your grandfather, a bit more difficult. If it is your great grandfather, it can be quite hard.

Your closest Greek Consulate [there are Consulates in NY, Boston, Tampa, Chicago, Atlanta, Washington, Houston, LA and San Fran] should be able to help you. But at the very minimum you should have the "closest direct ancestor" information before you call them...

Good luck!
