Hi. I am interested in getting a Greek passport. I am a US citizen. Both of my parents are from Greece but have become US citizens. How do I go about getting one? Thanks

You need to contact Greek consulate in your country...
Some factors, like whether you were born before of after your parents were naturalised, may play a factor, so you need to get specific advice...
It can be tedious - consulates aren't known for their customer service - but if you get a negative answer, make sure you check with another or higher official before giving up...

Thanks for your help. Im in the US,Chicago. So would I just physically go to the consulate? Would I not be able to get it if my parents became citizens before I was born? Thanks
