Greek Diaspora - Greek Nationality

Greek Nationality

Any person who is ethnically Greek born outside Greece may become a Greek citizen through naturalization, providing he/she can prove a parent or grandparent was born as a national of Greece. The Greek ancestor's birth certificate and marriage certificate are required, along with the applicant's birth certificate, and the birth certificates of all generations in between until the relation between the applicant and the person with Greek citizenship is proven.

Greek citizenship is acquired by birth by all persons born in Greece, and all persons born to at least one parent who is a registered Greek citizen. People born out of wedlock to a father that is a Greek citizen and a mother that is a non-Greek automatically gain Greek citizenship if the father recognizes them as his child before they turn 18.
