How can I get Greek Passport , and become a Greek citizen ?

You would have to become a Greek citizen firsst, then get a Greek passport. You need to contact the Embassy of Greece to Croatia or go to their website and learn how to apply to immigrate to Greece. I am sure it is a lengthy and detailed process...as it is to immigrate to ANY country. The Greek Embassy will be your best source of information.

In Ancient Greece, the definition of a Greek was based on whether someone wrote and thought in Greek. Today, I am delighted to see that Greek language is still a vital part of the process of becoming a Greek citizen.

was up ester!!! we have almost an identical avatar- sorry i dont know the answer but i will star so i can find out myself!

Don't misunderstand me, but...I think the quickest way is to marry a greek man, a greek citizen. (He could be of other origin, russian or something else). Another way is to stay permanent in Greece for a long time. Come here to study and...you'll find someone...

Marry Greek. Your husband will apply for you. 5 years after you become a citizen, you can apply for your passport. It's a long prosess.
