Dual citizenship in Greece: generally permitted
Greece receives a rating of 100 out of 100 points for allowing dual citizenship. Greek law generally permits a person to hold Greek citizenship together with another nationality.
Multiple citizenship is particularly relevant to people of Greek descent, families living abroad and long-term residents who naturalize. It can preserve family, professional and inheritance connections without an automatic Greek requirement to renounce every previous nationality.
The law of the other country remains decisive. Some states permit retention freely, while others require advance permission, impose loss rules or restrict multiple nationality in particular circumstances.
Permission to hold more than one nationality does not itself establish eligibility for Greek citizenship. Descent, birth, recognition, adoption and naturalization each have separate evidence and procedures.
What the legal classification means
The measured starting point is allowed. The displayed value describes the category “allowed” rather than a graduated barrier or cost figure.
Greece belongs to the international top group for this indicator. Greek citizens do not automatically lose citizenship merely by voluntarily acquiring another nationality.
Formal loss of Greek citizenship follows separate statutory conditions and an administrative decision. It should not be confused with automatic renunciation during naturalization.
Acquisition, retention and registration are separate steps
A child of a Greek parent can hold Greek citizenship by descent. In practice, registration in Greek civil and municipal records is often necessary before an identity card or passport can be issued.
Naturalization requires the qualifying lawful residence status, Greek language and civic knowledge and evidence of economic and social integration. Permission to retain an earlier nationality does not shorten those conditions.
Document chains are especially important in descent cases. Birth, marriage and name-change records must connect the applicant to the Greek ancestor and may require apostille, legalization or official translation.
Greek authorities generally treat a dual national as Greek when Greek citizenship applies. A second passport does not remove domestic rights and obligations.
Passports, military duties and family records
Male Greek citizens should clarify possible military-service duties and rules for permanent residents abroad with the responsible consulate. Multiple nationality does not create a general exemption.
Travelers should confirm which passport to use for entry, departure and interaction with each state. Different name spellings across passports can complicate tickets and registry procedures.
Tax liability does not arise from the passport alone. Residence, habitual presence, income and tax treaties require separate analysis, while inheritance and family law can involve more than one legal system.
Consulates and Greek registers
Greek consulates abroad assist with civil records, declarations and transmission of certain citizenship files. The substantive legal basis remains the Citizenship Code and the competent Greek authorities.
Municipalities, civil registries and regional citizenship directorates have different roles inside Greece. Jurisdiction follows the acquisition basis and existing registrations.
Families using different scripts, naming conventions or calendars should agree spellings before registration. Correcting inconsistencies later can take significant time.
What to check before making a decision
- Identify the legal basis for acquiring Greek citizenship.
- Check whether the other country permits retention.
- Match civil records and Greek registry entries without gaps.
- Clarify possible military and consular obligations.
- Review passport use, tax residence and name spelling separately.
What this indicator does not measure
The indicator only evaluates whether multiple citizenship is generally permitted. It does not measure naturalization time, descent evidence, processing or individual military and tax consequences.
It cannot decide whether the second country allows dual nationality or which citizenship a child receives at birth.
How to read the rating
The highest rating is justified for legal retention. Greece generally does not demand automatic renunciation of another nationality.
Practical work can still be substantial where citizenship must first be documented, an ancestry chain reconstructed or the other state requires retention permission.
Frequently Asked Questions
Must a person renounce existing citizenship when naturalizing in Greece?
Greece generally does not require automatic renunciation. The law of the other country must still be checked.
Is a child of a Greek parent automatically Greek?
Citizenship can arise by descent. Correct registration in Greek records is then important for documents.
Does a Greek passport automatically create Greek tax residence?
No. Tax residence depends mainly on residence, presence and income rather than citizenship alone.
Can dual nationality affect military obligations?
Yes. Male Greek citizens may need to consider military duties or overseas-resident rules and should consult the consulate.
