Greek parent already registered
We check the parent’s municipal record, your birth and the relevant family events before identifying the competent registration procedure.
GREEK ROOTS · CITIZENSHIP FROM ABROAD
Turn your Greek family history into a clear citizenship route.
For Greek Americans and families worldwide. We organise the evidence, trace the registration chain and identify the official path that fits the facts of your case.
Remote start · Secure case area · No guaranteed government outcome
Greek ancestor, incomplete chain
We build a generation-by-generation record map and flag missing births, marriages, name variations, translations or registrations for specialist review.
Previous refusal or complex facts
We organise the full history and evidence before a specialist-led assessment. No “loophole,” passport or approval is promised.
Private preparation, official decision
Greece One is not a ministry, municipality or consulate. Government fees, official processing and regulated professional work are separate unless expressly included in writing.
WHAT WE CHECK FIRST
A family chain, not a guess.
The correct route can depend on when citizenship existed in the family line and whether births and marriages were already entered in Greek records.
- 01Greek ancestor details
Full names, Greek birthplace, dates and known municipality or family registration. - 02Generation-by-generation records
Long-form birth and marriage records connecting you to the Greek parent or ancestor. - 03Consistency and legalisation
Name, date and place differences, apostille/legalisation status and translation needs. - 04Previous official history
Applications, decisions, consular correspondence and any refusal or pending file.

COMMON QUESTIONS
Know what is certain—and what must be checked.
Does a Greek grandparent automatically make me a Greek citizen?
Not necessarily. The answer depends on the family line, dates, marriages, existing Greek municipal registrations and the law that applies to each generation. We first map the chain before suggesting a procedure.
Can the process start from the United States?
Yes, the document and eligibility review can start remotely. Depending on the route, an official step may later be required through the competent Greek consulate, municipality or citizenship authority.
What if names or dates differ between Greek and foreign records?
Record differences are common and should be identified early. The competent authority or qualified professional determines whether corrections, additional evidence, legalisation or official translation are required.
Do you guarantee citizenship or a Greek passport?
No. Greece One is an independent private support service and does not make government decisions. We prepare and coordinate the agreed work; approval belongs exclusively to the competent Greek authority.
Verify the public procedure directly.
Requirements vary by legal route and personal history. These government pages are the authoritative starting points; opening them does not submit an application.
Start with the facts of your family.
Receive a preliminary direction before choosing a paid service. Do not send passport numbers, full identity documents or sensitive evidence through the public form.
