Greece allows both dual and multiple citizenship. Under the Greek Nationality Code, foreign nationals who become Greek citizens are not required to renounce their original nationality, and Greek citizens do not lose their citizenship when acquiring another nationality, provided the other country also permits dual citizenship.
A Greek passport provides the right to live, work, study, and settle across all 27 European Union member states, while also offering extensive global mobility. Whether you qualify through ancestry (jus sanguinis), naturalization after long-term legal residence, or the Greek Golden Visa as a pathway to eventual naturalization, dual Greek citizenship gives you a lasting connection to Europe for you and future generations.
This article will cover everything about Greek dual citizenship, from the legal pathways to eligibility criteria to specific rules for minor applicants and more.
Greek dual citizenship key takeaways
Does Greece allow dual citizenship?
Yes, Greece does allow dual citizenship. Greek nationality is governed by the Greek Nationality Code (Law No. 3284/2004), which establishes the legal framework for acquiring citizenship through birth, descent, or naturalization. The Code also allows dual citizenship through its provisions on the loss of nationality. Under these rules, Greek citizens do not lose their nationality when they acquire a foreign passport, and foreign nationals who naturalize as Greek citizens are not required to renounce their original citizenship, provided their home country also recognizes dual nationality.
Important Greek Immigration Law Changes 2026
Greece introduced Law 5275/2026 to adapt its immigration system, implement EU Directive 2024/1233, and better align residence permits with labor market needs. Key changes include:
- Unified Single Permits: Greece has introduced a single application process that combines work and residence authorization for highly skilled workers, dependent employees, and certain special-purpose permit holders. Applications must be processed within 90 days.
- Extended Renewal Grace Period: Residence permit renewal applications should be submitted within two months before the permit expires. If you miss the deadline, you now have up to three months after expiry to renew, although a €100 penalty applies for each month of delay.
- New Visa Categories: Law 5275/2026 introduces three new visa options:
- A Post-Study Permit, allowing graduates and researchers to stay in Greece for one year to find skilled employment or start a business.
- A Tech Visa for professionals employed by companies registered with Elevate Greece.
- A Talent Visa, granting highly qualified professionals up to 12 months to search for employment in Greece.
- Digital Nomad Rule Change: Applicants can no longer enter Greece on a tourist visa or visa waiver and apply for a Digital Nomad residence permit. A National D Visa is now required before arrival.
- Longer Permit Validity: The validity of the EU Blue Card has been extended from two to three years, while residence permits for partners of EU citizens are now valid for five years.

How to Obtain Dual Greek Citizenship
1. Citizenship by descent
The Greek citizenship by descent route acts as an automatic recognition of citizenship by birth under jus sanguinis. If an unbroken line to an ancestor in the municipal registry (Demotologion) is proven through ancestry records, the applicant is recognized as a citizen from birth. There are no language, integration, or residency requirements for this route.
2. Military Service
This is an expedited citizenship pathway reserved exclusively for individuals of proven Greek ethnic origin (Omogeneis). Volunteering for the Greek Armed Forces or enrolling in a Greek military academy grants Greek citizenship upon induction and bypasses the standard naturalization timeline.
3. Citizenship by Naturalization (Residency)
Citizenship by naturalization is the standard pathway for foreign nationals without Greek heritage. The main requirement is seven consecutive years of legal, continuous residence in Greece. Applicants must also pass the Panhellenic Examination for Naturalization, demonstrating intermediate (B1) Greek language proficiency and sufficient knowledge of Greek history, culture, and civic life.
4. Citizenship by Marriage
Marriage to a Greek citizen does not automatically lead to citizenship but provides access to an accelerated naturalization pathway.
- If the couple has a child: The residency requirement is reduced to three years of continuous, legal residence in Greece.
- If the couple does not have a child: The foreign spouse may apply after five years of legal residence, instead of the standard seven.
In both cases, applicants need to continue to live in Greece and successfully meet the mandatory language and civic integration requirements before citizenship can be given.
Dual Citizenship through the Greek Golden Visa
The Greece Golden Visa is one of Europe’s leading residency by investment programs, granting non-EU nationals permanent residence, visa-free travel across the Schengen Area, and family inclusion for a spouse, dependent children under 21, and both spouses’ parents. Applicants must be at least 18 years old, have a clean criminal record, and qualify through one of the following investment options:
- Prime Real Estate: €800,000+ for a single residential property (minimum 120 m²) in Athens, Thessaloniki, Mykonos, Santorini, and other designated high-demand areas.
- Regional Real Estate: €400,000+ for a single residential property (minimum 120 m²) in all other eligible regions.
- Special Real Estate Projects: €250,000+ for commercial-to-residential conversions or the restoration of listed historic buildings, with no minimum property size.
- Capital and Innovation Investments: €250,000+ in an Elevate Greece startup, €350,000+ in approved mutual funds, or €500,000+ in Greek bank deposits or government bonds.
The Path to Dual Citizenship
While the Greece Golden Visa has no minimum stay requirement to maintain residency, obtaining Greek citizenship requires genuine residence in the country. Eligible applicants can apply for citizenship after seven years of continuous legal residence, provided they have lived in Greece for at least 183 days per year, established tax residency, and passed the Panhellenic Examination for Naturalization, which includes B1-level Greek language proficiency and knowledge of Greek history, culture, and civic life

Greek Dual Citizenship for Minors
Under the Greek Nationality Code, minors (under 18) can acquire Greek citizenship through several streamlined pathways. Unlike adults, they are generally exempt from language and civic integration examinations.
- By Birth to a Greek Parent (Jus Sanguinis): A child automatically acquires Greek citizenship at birth if at least one parent is a registered Greek citizen.
- If the parents are unmarried, A child born to a Greek mother is automatically a Greek citizen. If only the father is Greek, citizenship is acquired once paternity is legally recognized before the child turns 18.
- By birth or education in Greece (Children of Foreign Parents): Children of foreign nationals can qualify for Greek citizenship through birth or education if they show strong ties to Greece.
- Born in Greece: Eligible if both parents legally resided in Greece for at least five consecutive years before the child’s birth and the child is enrolled in a Greek primary school.
- Educated in Greece: Children born abroad can qualify after completing either nine years of primary and secondary education or six years of secondary education at a Greek school.
- By adoption: A minor legally adopted by a Greek citizen automatically acquires Greek citizenship from the date the adoption becomes legally effective.
- Derivative Citizenship: Minor, unmarried children automatically acquire Greek citizenship when a parent is naturalized, provided they are under 18 at the time citizenship is granted.
Important documents for minor applicants
- Child’s birth certificate: Full, apostilled, and officially translated into Greek.
- Parents’ marriage certificate: Registered with the Greek Special Registry (Lixiarchio), where applicable.
- Parents’ identification: Valid passports and the Greek parent’s Family Status Certificate (Oikogeneiaki Merida).
- School attendance certificate: Required for applications based on education and issued by the regional Director of Education
Disadvantages of Having Dual Greek Citizenship
- Mandatory military service: Male Greek citizens aged 19 to 45 are generally required to complete up to 12 months of military service. Dual citizens who permanently live abroad can postpone their service until age 45, but staying in Greece for more than six months in a calendar year may end that exemption.
- Tax residency implications: Greek citizenship alone does not make you a Greek tax resident. However, living in Greece for more than 183 days per year establishes tax residency, which makes your worldwide income subject to Greek tax rules.
- Naturalization exam: Applicants pursuing citizenship through naturalization must pass the Greek citizenship test, also known as the Panhellenic Examination for Naturalization, demonstrating B1-level proficiency in Greek and knowledge of Greek history, geography, culture, and civic institutions
