Dual Citizenship
Croatia fully permits dual and multiple citizenship without any restrictions.
- Croatian citizens who acquire a foreign nationality retain Croatian citizenship automatically.
- Foreign nationals who naturalize as Croatian are not required to renounce their prior nationality.
- This policy has been in place since the 1991 Croatian Citizenship Act, adopted upon independence.
Croatia’s liberal approach reflects its large diaspora (estimated 2—4 million ethnic Croats living abroad, primarily in Bosnia and Herzegovina, Germany, Australia, Argentina, Chile, Canada, and the United States). The government actively facilitates citizenship acquisition by ethnic Croats worldwide.
Acquisition of Nationality
By Birth (Jus Soli)
Croatia does not apply a general jus soli principle. Birth on Croatian territory alone does not confer citizenship.
Exceptions (Article 7):
- A child born in Croatia acquires Croatian citizenship at birth if both parents are unknown or of unknown citizenship, or if the child would otherwise be stateless.
- Foundlings discovered on Croatian territory are deemed Croatian citizens until another nationality is established.
By Descent (Jus Sanguinis)
Croatian citizenship is the primary mode of acquisition and follows strict jus sanguinis (Article 4—6):
Automatic acquisition:
- A child acquires Croatian citizenship at birth if at least one parent is a Croatian citizen at the time of birth, regardless of where the child is born.
Children born abroad:
- If both parents are Croatian citizens, the child acquires citizenship automatically.
- If only one parent is Croatian and the other is a foreign national, and the child is born abroad, citizenship is acquired automatically if:
- The child is registered at a Croatian diplomatic or consular mission by age 18, OR
- The child would otherwise be stateless.
- If not registered by age 18, the child may apply for citizenship up to age 21.
Ethnic Croatian descent (Article 11):
This is one of Croatia’s most distinctive provisions. A member of the Croatian people (pripadnik hrvatskog naroda) who does not have Croatian citizenship may acquire it by declaration, without any residency requirement, if they demonstrate:
- Membership in the Croatian ethnic nation (Croatian ancestry, ethnic identity, cultural affiliation).
- Adherence to the Croatian legal order and customs.
- This is not naturalization — it is acquisition by origin and requires no residence in Croatia, no language test, and no civics exam.
- Dual citizenship is fully permitted under this pathway.
This provision has been widely used by ethnic Croats in Bosnia and Herzegovina (an estimated 500,000+ Bosnian Croats hold Croatian citizenship) and by members of the Croatian diaspora worldwide.
By Adoption
A child under 18 adopted by a Croatian citizen acquires Croatian citizenship upon the adoption becoming effective under Croatian law (Article 13):
- Applies to full adoption.
- The child must be a minor at the time of the adoption.
- Adults adopted by Croatian citizens do not acquire citizenship through adoption.
By Marriage
Marriage to a Croatian citizen does not automatically confer citizenship. The foreign spouse may apply for naturalization with a reduced residency requirement:
| Requirement | Details |
|---|---|
| Residence | No minimum residency in Croatia required if the couple resides abroad; if in Croatia, must have registered residence |
| Marriage duration | At least 3 years of continuous marriage |
| Language | Croatian language proficiency (demonstrated at interview or by certificate) |
| Criminal record | No convictions that would bar naturalization |
| Renunciation | Not required — dual citizenship permitted |
Note: The spousal pathway is one of the most accessible in the EU, particularly for couples residing outside Croatia. The applicant must demonstrate a genuine connection to Croatia through the marriage but is not required to live in the country.
By Naturalization (Residency)
Standard pathway (Article 8):
| Requirement | Details |
|---|---|
| Lawful residence | 8 years of continuous lawful residence in Croatia |
| Language | Croatian language and Latin script proficiency |
| Civics knowledge | Knowledge of Croatian culture, social system, and constitutional order (assessed by test) |
| Criminal record | No convictions for criminal offenses in Croatia; no pending proceedings |
| Financial self-sufficiency | Confirmed source of income sufficient for self and dependents |
| Respect for legal order | Must not pose a threat to public order or national security |
| Renunciation | Not required — dual citizenship permitted |
| Fee | HRK 1,050 (approximately EUR 140) |
Reduced pathways:
| Category | Residence Requirement |
|---|---|
| Spouse of Croatian citizen | No minimum (see above) |
| Ethnic Croatian (Article 11) | None — acquisition by declaration |
| Persons born in Croatia | 5 years |
| Refugees and stateless persons | 5 years |
| Special contribution to Croatia | Discretionary — no minimum |
Loss and Renunciation
Voluntary Renunciation
A Croatian citizen may renounce citizenship by filing a request with the Ministry of the Interior (Article 22), provided:
- They are 18 years or older.
- They hold another nationality or have been assured one.
- They have no outstanding tax or military obligations to Croatia.
The renunciation becomes effective upon issuance of a formal decision by the Ministry.
Involuntary Loss
| Ground | Details |
|---|---|
| Acquisition by fraud | Citizenship obtained through false statements, fraudulent documents, or concealment may be revoked (Article 20). |
| Voluntary foreign military service | A Croatian citizen who voluntarily enters the military service of a foreign state without authorization may lose citizenship (Article 17). |
Important: Croatia does not revoke citizenship for voluntary acquisition of a foreign nationality.
Restoration of Nationality
Former Croatian citizens who lost their citizenship by renunciation or deprivation may apply for re-acquisition (Article 15):
- Must file a request with the Ministry of the Interior.
- Must demonstrate a connection to Croatia (residence, family ties, or ethnic Croatian identity).
- No minimum residence requirement if the applicant is an ethnic Croat.
- Standard residency requirements may be reduced at the Ministry’s discretion.
- Dual citizenship is permitted upon re-acquisition.
Emigrants and diaspora: Ethnic Croats who never held Croatian citizenship but can demonstrate Croatian descent may acquire citizenship under Article 11 (see “By Descent” above), which is effectively a restoration pathway for the diaspora.
Stateless Persons and Foundlings
- Foundlings discovered on Croatian territory are deemed Croatian citizens until another nationality is established (Article 7).
- Stateless children born in Croatia acquire Croatian citizenship at birth.
- Stateless adults may apply for naturalization after 5 years of lawful residence (reduced from the standard 8 years).
- Croatia is a party to the 1954 Convention relating to the Status of Stateless Persons and the 1961 Convention on the Reduction of Statelessness.
