How to Get Greek Dual Citizenship by Descent or Naturalization

Greek dual citizenship is allowed: Greece does not require you to renounce any other nationality when you become Greek, so you can hold a Greek passport alongside your current one and use it to live, work, and travel throughout the EU and EEA. The practical route to it depends on your situation. Most people qualify through Greek ancestry, some through years of legal residency in Greece, and others through marriage to a Greek citizen. Before you commit to any of them, know that Greece will treat you as a full citizen on Greek soil, which brings tax rules and, for men, potential military service into play.

Citizenship by Descent

Descent is the fastest and cleanest path if you have a Greek parent or grandparent. A child of a Greek father or Greek mother acquires Greek citizenship at birth, with no strict generational cap, though the paperwork gets heavier the further back your Greek ancestor sits.

When a Parent Is Greek

If either parent is a registered Greek citizen, you’re generally entitled to citizenship by descent. The controlling question is whether at least one parent appears in a Greek municipal family record, called a merida. If they do, you can typically be added to that record as their child, either directly or after a decision by the local Citizenship Service.

A few date rules still matter. For anyone born before July 16, 1982, citizenship through a Greek father passed only to children born within a marriage; after that date, marital status no longer matters. On the mother’s side, children born before May 8, 1984 to a Greek mother did not receive citizenship automatically but could claim it by filing a declaration at the local prefecture or a Greek consulate. Births after May 8, 1984 to a Greek mother are automatic.¹

Where parents were not married, citizenship is automatic if the mother is Greek (post-1984). If only the father is Greek, the child must first be recognized through a voluntary acknowledgment or court-ordered paternity determination.¹

When the Link Runs Through a Grandparent

If your Greek ancestor is a grandparent, citizenship must flow in an unbroken chain from the registered Greek ancestor down to you. Normally the parent of Greek descent has to establish their own citizenship first, and then you apply as their child. If that parent is deceased and never registered as Greek, you may need to pursue naturalization as a person of Greek ethnic origin instead, supported by the same chain of birth, marriage, and death certificates plus proof of the ancestor’s municipal registration.²

Finding the Municipal Record

Every descent claim hinges on your ancestor’s registration in a Greek municipal record. Without it, the file goes nowhere. If you know the village or town of origin, contact that municipality directly, or ask the nearest Greek consulate to open a search. Bring as much as you have: full name (in Greek if possible), approximate birth year, parents’ names, and region. Greek Orthodox baptism certificates, old Greek passports, and Greek-language family documents all help locate the right record.

Citizenship by Naturalization

If you have no Greek ancestry, the standard route is naturalization after seven continuous years of legal residency in Greece.³

The residency period drops to three years for:

Foreign nationals married to a Greek citizen with whom they have a child.
Refugees and stateless persons formally recognized by Greek authorities.
Foreign nationals of documented Greek ethnic origin who don’t qualify for citizenship by descent.

Every naturalization applicant must be at least 18, have no pending deportation order, and have no serious criminal convictions in the ten years before applying. Disqualifying offenses include violent crimes, drug trafficking, fraud, forgery, smuggling, and human trafficking, among others.⁴

The Citizenship Exam

Naturalization applicants must pass the Panhellenic Citizenship Exam, which tests Greek language plus history, geography, culture, and political institutions. It has written questions, oral questions, and an essay, with a minimum passing score of 80%. It’s offered periodically and requires advance registration. The exam is not required if you’re applying through descent.

Citizenship Through Marriage

Marrying a Greek citizen does not by itself make you Greek. It opens a naturalization pathway with a shorter residency requirement: three years of marriage combined with continuous legal residency in Greece, and you still have to meet the standard naturalization criteria, including the exam.³

Greece also recognizes registered partnerships for residence purposes. A third-country national in a registered partnership with a Greek citizen can apply for a residence card on the same basis as a spouse, which provides the legal residency foundation for eventual naturalization.⁵

Documents You’ll Need

Applications stall most often over missing or incomplete paperwork. The exact list depends on your path, but every application needs identity verification, proof of lineage or residency, and evidence of good legal standing.

For citizenship by descent, expect to provide your birth certificate showing a Greek-descent parent, birth and marriage certificates for each generation linking you to your Greek ancestor, death certificates for deceased ancestors in the chain, proof of the ancestor’s Greek registration (municipal record extract, baptism certificate, or old Greek passport), and your current valid passport.²

For naturalization, you’ll need proof of legal residency for the required period (residence permits and tax returns), a criminal record certificate from your country of origin, proof of citizenship exam results, and financial documentation such as tax filings and bank statements.³

Criminal Record Certificates

Criminal record certificates are valid for three months, so don’t order one too early or it will expire before your file is reviewed.⁶ U.S. applicants need an FBI Identity History Summary, which costs $18 and can be submitted electronically. The FBI processes requests in the order received with no guaranteed turnaround, so plan ahead.⁷

Translation and Apostille

Every document not in Greek must be translated by a certified translator, roughly $20 to $30 per page for English to Greek. Documents issued outside Greece also need an apostille. Greece is party to the Hague Apostille Convention, so an apostille from any other member country is accepted without further legalization.⁸ In the United States, apostilles for federal documents like FBI background checks come from the U.S. Department of State; apostilles for state documents like birth certificates come from the secretary of state in the issuing state, with fees typically $10 to $26.

Where to File, What It Costs, How Long It Takes

If you live outside Greece, file through the nearest Greek Embassy or Consulate. If you live in Greece, file with your local Municipal Office or Regional Directorate of Citizenship. Book the appointment in advance.

Fees depend on category. Standard naturalization is €700 for the first application, dropping to €200 on a reapplication. Refugees and stateless persons pay €100. Naturalization for persons of Greek ethnic origin filed through a consulate abroad runs about €140.³ Fees for descent registrations vary by consulate and municipality, so confirm the current figure with the office handling your case.

Descent cases are the fastest, generally six months to two years since the work is largely verifying family records. Naturalization has a one-year statutory processing period on paper but usually takes two to four years in practice.³ Authorities may ask for additional documents or an interview along the way. Respond quickly, because delays on your end add to the total.

Once approved, you take an oath of allegiance to the Greek Republic, and your name is entered in the Municipal Registry and the National Citizen Registry. From there you can apply for a Greek passport and national identity card.

Military Service if You’re Male

This is the piece that catches many new dual citizens off guard. Greek law requires all male citizens between the ages of 19 and 45 to perform military service, and the obligation applies to anyone Greece considers a citizen regardless of a second passport, birth abroad, or never having lived in Greece.⁹

Standard service is 12 months. A nine-month reduced term is available to those who volunteer for early induction or serve in designated high-priority zones such as Thrace, the Eastern Aegean islands, or the Presidential Guard.

Long-term residents abroad may qualify for a postponement or exemption. Someone with permanent residence outside Greece for at least 11 consecutive years, or seven consecutive years abroad for work or other living needs, can apply for a Certificate of Permanent Residence Abroad through a Greek consulate or the Armed Forces Department.⁹

Noncompliance has real consequences. Men who haven’t served or been exempted can be blocked from routine business in Greece, including renewing a passport or accessing consular services. If you’re male and considering Greek citizenship, ask the nearest Greek consulate about your military status before you finalize the application.

Tax Reporting for U.S. Dual Citizens

Americans who acquire Greek citizenship and open Greek bank accounts or hold other Greek financial assets pick up U.S. reporting requirements that carry steep penalties for noncompliance.

If the combined value of all your foreign financial accounts exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) with the Financial Crimes Enforcement Network.¹⁰

FATCA reporting on Form 8938 kicks in at higher thresholds. If you live in the United States, you report specified foreign financial assets over $50,000 on the last day of the tax year or $75,000 at any point during the year. If you live abroad, single filers’ thresholds are $200,000 and $300,000 respectively.¹¹

Those are U.S. obligations. Greece has its own tax residency rules; spending more than 183 days per year in Greece can make you a Greek tax resident with Greek filing obligations as well. If you’re moving assets or planning to spend significant time in Greece, a tax professional familiar with both countries is worth the fee.
