Jure Sanguinis Citizenship

Greek citizenship by descent, known as jure sanguinis (right of blood), is the legal recognition that you are a Greek citizen by virtue of your ancestry. Under the Greek Nationality Code, citizenship is considered an inherent right passed down through generations; the Greek state does not "grant" you this status, but rather "recognizes" a right that has existed since your birth.

This pathway is for individuals who can prove they have at least one ancestor—a parent, grandparent, or even great-grandparent—who was registered as a citizen in a Greek municipality. Because Greek law has undergone significant changes regarding gender equality and marriage recognition, your specific eligibility depends heavily on the year you were born and the marital status of your ancestors.

• The "Broken Chain": If an ancestor formally renounced their Greek citizenship or naturalized in another country before 1984 without the required Greek government permission, they may have legally lost their Greek status, potentially breaking the chain for their descendants.
• Marriage Validity: Before July 16, 1982, Greece primarily recognized religious marriages. If your ancestors had a civil marriage before this date, it may require specific legal "Declaration" steps to be recognized for citizenship purposes.
• Military Service: Male citizens between the ages of 19 and 45 are liable for military service. However, if you are a Permanent Resident Abroad, you can typically obtain a deferment or exemption. Note that having an unresolved military status may limit the duration of your stays in Greece.
• Name Discrepancies: If your ancestor’s name changed after they emigrated (e.g., "Ioannis" became "John"), you may need a "Certificate of One and the Same Person" or legal affidavits to prove they are the same individual listed in Greek records.

• EU Freedom of Movement: You gain the right to live, work, and study in any of the 27 European Union member states without a visa.
• Consular Protection: You are entitled to protection and assistance from Greek and EU embassies and consulates worldwide.
• Dual Citizenship: Greece fully permits dual nationality. You are not required to give up your current citizenship to become Greek.
• Family Reunification: Your minor children (under age 18) typically acquire Greek citizenship automatically once your own registration is finalized.
• Voting and Public Office: You have the right to vote in Greek national and European Parliament elections and to run for public office in Greece.
• Access to Services: You have full access to the Greek national healthcare system (ESY) and the right to pay "home student" tuition rates at European universities.
