There are several ways to acquire Croatian citizenship: through naturalisation following a minimum of eight consecutive years of residence (of which at least three must be as a permanent resident), through ancestry for those who can trace Croatian lineage, and through marriage to a Croatian national. Croatia generally allows dual citizenship for those obtaining it via descent or as a matter of national interest, while applicants going through the standard naturalisation process are typically expected to surrender their prior nationality where this is legally possible.

Who is eligible to apply for citizenship in Croatia?
Non-Croatian nationals — that is, those who do not already hold Croatian citizenship — may lodge an application to acquire it through naturalisation, provided they satisfy the conditions set out in the Croatian Citizenship Act. The law establishes a number of distinct pathways, and which one applies will depend entirely on your individual situation.
Naturalisation by residence
To be eligible for naturalisation on the basis of residency, you must have resided in Croatia without interruption for a minimum of eight years and hold permanent resident status. You must also show adequate knowledge of the Croatian language, Latin script, culture, and legal framework. Applicants must be at least 18 years of age at the time they apply. By comparison, the United Kingdom requires five years of lawful residence and Australia requires four — making Croatia’s eight-year threshold considerably more demanding than many equivalent countries.
Those aged over 60 are not required to demonstrate knowledge of the Croatian language and culture. Applicants must also show that they comply with Croatia’s legal order by meeting their public financial obligations, and there must be no security-related grounds preventing the grant of citizenship.
Citizenship by descent
The descent pathway allows individuals around the world who can establish Croatian ancestry to claim citizenship, regardless of whether they were born in Croatia. Croatia permits people to acquire citizenship through parents, grandparents, or even great-grandparents — a principle commonly known as jus sanguinis, or right of blood.
Descendants of grandparents who left the territory of the Republic of Croatia prior to 8 October 1991 may claim citizenship if they are able to establish both the family connection and the emigration. Descendants of great-grandparents who departed before that date may also be eligible, though this involves a more involved process requiring thorough documentary evidence of lineage and emigration history.
An applicant may be ineligible for citizenship by descent if their ancestor left Croatia to settle elsewhere within Yugoslavia or the former Yugoslav states. In general, Article 11 of the Croatian Citizenship Act does not extend to migrants who became citizens of other territories of the former Yugoslavia.
Citizenship through marriage or civil partnership
Marriage to a Croatian citizen is another recognised pathway to citizenship. Foreign nationals who are married to Croatian citizens may apply after three years of marriage and three years of residence in Croatia. Demonstrating genuine cohabitation, shared domestic arrangements, and meaningful integration into Croatian life are all essential components of this type of application. Civil partners are equally entitled to apply, and the relevant extract from the Register of Civil Partnerships must be included as part of the supporting documents.
Citizenship in the national interest or for exceptional contribution
Foreign nationals whose acquisition of Croatian citizenship would serve the interests of the Republic of Croatia may apply even where the standard requirements under Article 8 — such as minimum age, permanent residence, language ability, or renunciation of prior citizenship — have not been met. Croatia may, on a discretionary basis, grant citizenship to individuals considered to be of strategic value — such as eminent scientists, elite athletes, major investors, or prominent cultural figures. This route is uncommon and requires a recommendation at ministerial level followed by government approval.
Citizenship by birth
Under Article 4 of the Law on Croatian Citizenship, a child acquires Croatian citizenship by origin if both parents are Croatian citizens at the time of the child’s birth; if one parent is a Croatian citizen at the time of birth and the child is born in the Republic of Croatia; or if one parent is a Croatian citizen and the other is stateless or of unknown citizenship, and the child is born abroad.
What are the steps involved in applying for citizenship in Croatia?
The process of acquiring Croatian citizenship is administered by the Ministry of the Interior at its central offices. While the precise steps differ depending on which route you are taking, the general procedure below applies to the majority of applicants. Always consult the Ministry of the Interior’s official website for current requirements, since fees and procedures are subject to change.
- Establish which route applies to you. Begin by identifying whether your application will be based on residence-based naturalisation, ancestry, marriage, or another qualifying ground. Each pathway carries different document requirements and timelines, so pinning this down before you begin gathering paperwork will prevent unnecessary delays.
- Assemble your supporting documentation. The essential documents include a curriculum vitae and a letter of motivation for acquiring Croatian citizenship, a certified copy of a valid photo identity document, proof of citizenship status, and an extract from the register of births issued in the standard format in accordance with applicable international agreements and conventions. You will also need a certificate of no criminal record from the relevant authority in both your country of citizenship and your country of permanent residence — either an original or a duly certified copy accompanied by a Croatian translation, and issued within the preceding six months.
- Obtain legalisation or an apostille for foreign documents. Foreign public documents submitted with your application must first be legalised, unless an applicable bilateral or multilateral international agreement provides otherwise. For countries that are parties to the Hague Convention of 5 October 1961 (the Apostille Convention), it is sufficient for the document to be authenticated once by the appropriate authority in the country where it was issued.
- Lodge your application in person. Applications for Croatian citizenship by naturalisation must be submitted in person at the police administration or police station with jurisdiction over the location where your temporary or permanent stay has been granted. If you do not hold granted temporary or permanent stay in Croatia, the application is submitted through a Croatian diplomatic mission or consular post abroad. As an exception, applicants with a disability may have their application submitted by their legal representative or an authorised person on their behalf.
- Pay the applicable administrative fee. A fee is due upon receipt of the decision on your citizenship application. Administrative charges currently fall in the range of €100–€300, and you should also factor in costs for document translation, certification, and any legal representation you engage. Always verify the current fee schedule on the Ministry of the Interior’s official website, as these amounts may be updated.
- Wait for a decision to be reached. The status of your application can be checked by submitting a written enquiry by post or email. Croatia is known for particularly lengthy processing periods, and many applicants wait two years or more — a timeframe that can be extended further when applications are lodged from abroad.
- Receive your decision and complete your registration as a citizen. Foreign nationals obtain Croatian citizenship on the date on which a positive decision is delivered to them. Following delivery of the decision, the applicant is recorded in the Register of Citizens at the competent registry office, and the certificate of citizenship is then issued at that office.
What tests, interviews, or ceremonies are required as part of the citizenship process in Croatia?
The Croatian citizenship assessment actually consists of two separate evaluations: one measuring your command of the Croatian language, and another assessing your familiarity with Croatian culture and history. These tests are required for applicants pursuing citizenship on the basis of residence through naturalisation. Those applying exclusively on descent-based grounds are generally not required to sit either of them.
The Croatian language test
The language examination is pitched at B1 level and covers comprehension, reading, writing, speaking, and grammar. This B1 standard equates to a broadly intermediate level of competency — similar to the language benchmarks used by countries such as Germany and the Netherlands in their own naturalisation frameworks. Knowledge of Croatian and the Latin script may alternatively be evidenced by a certificate of having passed an approved exam at a university or faculty offering Croatian language programmes, or through certificates issued by secondary schools, the National Centre for External Evaluation of Education, or accredited adult education institutions.
The language test is conducted by the Faculty of Humanities and Social Sciences at the University of Zagreb, the Faculty of Humanities and Social Sciences at the University of Rijeka, the Faculty of Humanities and Social Sciences at Josip Juraj Strossmayer University of Osijek, and other institutions holding the appropriate accreditation. The Ministry of the Interior’s website publishes a current list of approved testing bodies.
The following groups are exempt from the language and script examination: children of preschool age, individuals who are attending or have completed primary, secondary, or higher education within the Republic of Croatia, and individuals over the age of 65 who are not in employment.
The cultural knowledge questionnaire
Knowledge of Croatian culture and social structure is assessed through a questionnaire that the applicant completes independently and without assistance, in the presence of a police official. This is carried out as part of the citizenship application process rather than as a separate exam held at an external institution.
Background checks and security vetting
Every applicant is subject to a background check. Criminal record certificates from both the applicant’s country of citizenship and their country of permanent residence — in the form of originals or duly certified copies accompanied by Croatian translations, and issued within the preceding six months — are compulsory. Croatian authorities also undertake their own security screening to confirm that there are no grounds relating to public order or national security that would preclude the grant of citizenship.
Interviews and home visits for marriage-based applications
Where citizenship is sought on the basis of marriage, authorities place significant weight on evidence of genuine shared family life, joint accommodation, and meaningful integration. Officials conduct interviews and may carry out home visits to verify that the relationship is authentic. There is no formal sworn oath ceremony in Croatia comparable to the public citizenship ceremonies conducted in countries such as Canada or Australia — citizenship comes into effect from the date on which the positive decision is delivered to the applicant.
What are the benefits of citizenship in Croatia?
Acquiring Croatian citizenship brings with it an extensive array of rights and practical advantages that reach well beyond those available to permanent residents or visa holders. Given that Croatia has been a member of the European Union since 2013, Croatian citizenship simultaneously confers EU citizenship — a benefit of considerable significance.
EU citizenship and freedom of movement
By virtue of Croatia’s membership of the European Union, Croatian citizens are also EU citizens under EU law and consequently enjoy rights of free movement and the right to vote in European Parliament elections. Under Article 21 of the EU Treaty, Croatian citizens are entitled to live and work in any EU member state. This is among the most valuable benefits — particularly for those with ambitions to relocate or pursue careers elsewhere across the bloc.
A highly ranked passport
As of 2026, Croatian citizens benefit from visa-free or visa-on-arrival access to 182 countries and territories, placing the Croatian passport 7th globally according to the Henley Passport Index. This includes access to destinations such as Japan, Canada, and Australia. For citizens of countries with more limited passports, this represents a substantial enhancement of international mobility.
Consular protection across the EU
When in a non-EU country where Croatia has no embassy or consulate, Croatian citizens are entitled to seek consular protection from the diplomatic mission of any other EU member state present in that country. This provides a meaningful safety net for those who travel frequently to destinations where Croatia lacks a diplomatic presence.
Healthcare, social services, and education
As EU citizens, Croatian nationals have access to healthcare and social services throughout the EU, including the European Health Insurance Card (EHIC), which enables them to receive medical treatment in other member states at reduced cost. They also enjoy full entitlement to Croatia’s domestic public health system and social benefits, as well as the right to enrol in state educational institutions on the same terms as any other citizen.
The right to vote and stand for election
Croatian citizens may vote in national and local elections in Croatia, as well as in European Parliament elections. They may also put themselves forward as candidates in Croatian elections and take up public sector roles that are restricted to citizens — including certain positions in law enforcement, the civil service, and the judiciary.
Access to higher education and student mobility
Croatian nationals can pursue studies in any European country without navigating complex administrative procedures. They are not required to obtain or renew a student residence permit annually. Croatian citizens are also eligible to participate in the Erasmus programme, giving them the opportunity to spend one or two semesters studying at a university in another country.
Does Croatia allow dual citizenship, or will you have to renounce your existing nationality?
The answer turns on how you are obtaining Croatian citizenship, and it is essential to understand the rules from both directions: Croatia’s own stance and that of your country of origin.
Croatia’s position on dual nationality
Croatia does not compel its own citizens to relinquish their Croatian nationality when they take on a new citizenship elsewhere. The position is different, however, when acquiring Croatian citizenship: under Article 8 of the Law on Croatian Citizenship, naturalisation into Croatian citizenship requires the applicant to relinquish their previous nationality, to the extent that the other country permits this.
This renunciation requirement does not apply in several circumstances — notably for descendants of Croatian emigrants, for those being granted citizenship in Croatia’s national interest, and for former Croatian citizens who gave up their citizenship in order to pursue a professional career in another country. In practice, this means that applicants obtaining citizenship by descent are generally in a position to hold both nationalities simultaneously.
Where a foreign country does not allow dismissal from its citizenship, or imposes conditions on dismissal that cannot be met, a declaration from the applicant of their intention to renounce their foreign citizenship once Croatian citizenship is granted will be accepted as sufficient.
Your home country’s rules
It is equally important to establish whether your existing country of nationality permits dual citizenship. The rules differ considerably from one country to another: some automatically withdraw citizenship upon voluntary naturalisation in another state, while others impose no restriction whatsoever. Before submitting an application for Croatian citizenship, you should contact the relevant immigration or foreign affairs authority in your home country to understand what effect, if any, naturalisation in Croatia would have on your existing nationality. This is your own responsibility to investigate — Croatian authorities will not advise you on another country’s citizenship legislation.
How long does it typically take to become a citizen of Croatia?
As a general rule, the journey to Croatian citizenship spans at least eight years from the point of first taking up residence — and that is before accounting for the time needed to process the application itself. The precise timeframe varies considerably depending on which pathway you are pursuing.
Residency-based naturalisation
A temporary residence permit is initially valid for one year and may be extended. Converting this to permanent residency requires at least five years of living in Croatia. Once permanent residency is established, you must continue to reside in Croatia continuously for a total of at least eight years — including a minimum of three years as a permanent resident — before becoming eligible to apply. After submission, the Ministry of the Interior typically takes one to two years or more to reach a decision, as of 2025.
Descent-based applications
For those who can demonstrate Croatian ancestry, the route to citizenship is reasonably well-defined — though the processing period alone means the journey from submission to receiving a decision typically spans two to three years. There is no minimum residency requirement for descent-based applicants, which means the process can be initiated without first establishing a home in Croatia.
Marriage-based applications
Foreign nationals married to Croatian citizens may apply after three years of marriage combined with three years of residence in Croatia. Once submitted, these applications are also subject to processing times in the region of one to two years or more (as of 2025). For up-to-date estimates, consult the Ministry of the Interior website directly, as these figures are liable to change.
| Route | Minimum qualifying period | Typical processing time |
|---|---|---|
| Naturalisation (residence) | 8 years continuous residence (incl. 3 years permanent residency) | 1–2+ years |
| Descent (Article 11/16) | No minimum residency required | 2–3+ years |
| Marriage to Croatian citizen | 3 years of marriage + 3 years residence | 1–2+ years |
| Special/national interest | Discretionary — no standard period | Variable |
What are the main reasons an application for citizenship in Croatia might be refused?
The Ministry of the Interior may decline a citizenship application on a range of grounds. Familiarising yourself with these in advance and ensuring that your application is thorough and accurately documented is the most effective way to minimise the risk of rejection. Incomplete documentation is the most frequent cause of both delays and refusals.
- Criminal record. A significant criminal history — whether in Croatia or in another country — constitutes a serious ground for refusal. Every applicant must demonstrate that there are no security-related obstacles to the grant of citizenship, and criminal record certificates from both the country of citizenship and the country of permanent residence are mandatory components of the application.
- Insufficient or interrupted residency. Applicants must have maintained registered residence in Croatia without interruption for at least eight years and must hold foreigner status with permanent residence. Any gaps in registered residence, or periods spent outside Croatia that break the continuity requirement, can lead to refusal or require the applicant to restart the qualifying period from scratch.
- Failure to meet language or cultural knowledge requirements. Applicants who cannot demonstrate sufficient proficiency in Croatian or who do not satisfactorily complete the cultural knowledge questionnaire will not fulfil the conditions for naturalisation.
- Failure to release from previous citizenship. Where standard naturalisation is being sought, failure to provide evidence of release from a prior citizenship — or confirmation that such release will be obtained — may result in refusal, unless a recognised exemption applies to the applicant’s circumstances.
- Incomplete or fraudulent documentation. Any inaccuracy, omission, or indication of fraud in the application will lead to a refusal. All foreign documents must be properly legalised or apostilled and submitted alongside certified Croatian translations.
- Security-related concerns. Where Croatian authorities identify concerns relating to public order or national security, citizenship may be denied on those grounds.
Where an application is refused, applicants generally have the right to contest the decision through Croatian administrative law procedures. Independent legal advice should be sought before pursuing an appeal, as the process involves lodging a formal administrative complaint and potentially bringing the matter before the Administrative Court. The timelines associated with appeals can add substantially to the overall length of the process.
Where can you find reliable, up-to-date information about citizenship in Croatia?
Croatian citizenship law and administrative procedures evolve over time, and information that was accurate twelve months ago may no longer reflect the current position. For authoritative and current requirements, fees, and processing timelines, only official Croatian government sources should be relied upon.
- Ministry of the Interior (Ministarstvo unutarnjih poslova — MUP): The citizenship application process is administered by the Ministry of the Interior centrally. Their official website at mup.gov.hr is the principal source for application forms, lists of required documents, and procedural guidance. Note that certain sections of the site are available in Croatian only, so a certified translator may be required.
- Croatian Government portal (gov.hr): The official government information portal at gov.hr offers an overview of the citizenship acquisition process and links through to more detailed guidance published by the Ministry of the Interior.
- Croatian diplomatic missions and consular posts: If you are applying from outside Croatia, the Croatian embassy or consulate nearest to you is the appropriate point of contact. They can provide current guidance tailored to applications submitted from abroad.
- Ministry of Foreign and European Affairs (Ministarstvo vanjskih i europskih poslova): The Ministry of Foreign Affairs website contains contact details for Croatian embassies and consulates worldwide.
For more complex situations — in particular, descent-based applications involving historical records or multi-generational ancestry — engaging a qualified Croatian immigration lawyer is strongly advisable. A specialist can assess your specific eligibility and guide you in compiling the correct documentation from the very beginning, avoiding costly errors.
Frequently asked questions about Croatian citizenship
Do children born in Croatia automatically receive Croatian citizenship?
A child acquires Croatian citizenship by origin if both parents are Croatian citizens at the time of birth, if one parent is a Croatian citizen and the child is born in the Republic of Croatia, or if one parent is a Croatian citizen and the other is stateless or of unknown citizenship and the child is born abroad. Birth on Croatian territory alone is not sufficient to confer citizenship — at least one parent must hold Croatian citizenship at the time of the child’s birth.
Can Croatian citizenship be lost or revoked?
Croatian citizenship can end in two ways: through release from citizenship (known as otpust) or through renunciation of citizenship (known as odricanje). Those who are released from citizenship may reapply at a later date. Citizenship may additionally be revoked where it was obtained through fraud, misrepresentation, or the submission of false documents.
What happens to a citizenship application if the applicant moves abroad during the process?
Relocating abroad after submitting a naturalisation application can seriously jeopardise your case, particularly for residence-based applications where uninterrupted residence in Croatia is a fundamental requirement. The Ministry of the Interior processes applications centrally, but losing your registered residence status in Croatia could result in your application being refused. Before making any such move, you should seek advice from a Croatian immigration lawyer. Applicants pursuing the descent route are in a different position and are not subject to this concern, as they may apply from abroad.
Is there an investment-based or “golden visa” route to Croatian citizenship?
Croatia does not operate a citizenship by investment programme. Purchasing property may assist in obtaining a residency permit but does not provide a direct route to citizenship. Investors who are deemed to be of strategic value to Croatia may be considered under the national interest route, but this is entirely discretionary, extremely rare, and contingent on ministerial recommendation and government approval.
Can children be included in a parent’s citizenship application?
Underage children may acquire Croatian citizenship through naturalisation if both parents obtain citizenship through naturalisation; if one parent alone obtains citizenship through naturalisation and the child is resident in Croatia with permanent residence; or if one of the parents acquires citizenship through naturalisation pursuant to Article 11(1) or Article 16 of the Croatian Citizenship Act. Written consent from the other parent is generally required in relevant cases.
Do I need to speak Croatian to apply for citizenship by descent?
The requirements relating to language and cultural knowledge apply principally to those applying for citizenship through naturalisation based on residence. Descent-based applicants may submit their application without satisfying the residency-linked language requirement, though the letter of motivation and personal biography forming part of the application must be written in Croatian — meaning a working knowledge of the language, or the assistance of a certified translator, is necessary in practice.
Can I apply for Croatian citizenship if I was adopted by Croatian citizens?
Children adopted by Croatian citizens may be eligible for Croatian citizenship. The precise pathway will depend on the specific circumstances of the adoption and whether one or both adoptive parents hold Croatian citizenship. For confirmation of which route applies and what documentation is required in your case, you should consult the Ministry of the Interior directly or seek advice from a Croatian immigration lawyer.
Does holding permanent residency in Croatia automatically lead to citizenship?
Permanent residency grants you the right to remain in Croatia indefinitely and does not require you to pursue citizenship unless that is your wish. While permanent residency is a prerequisite for naturalisation, it does not automatically confer citizenship — you must independently satisfy all applicable conditions and submit a formal application in order to be considered.
What is the “Domovnica” and when do I receive it?
The Domovnica is Croatia’s official certificate of citizenship, serving as formal documentary proof of Croatian nationality. Following the acquisition of citizenship and registration in the Registry of Citizens of the Republic of Croatia, the certificate may be collected from any registry office in the country. It is a key document that you will need when applying for a Croatian passport.
Once I have Croatian citizenship, do I need to live in Croatia to keep it?
Croatian citizenship, once granted, is permanent. There is no requirement to maintain residence in Croatia in order to retain it. Croatian citizens who live abroad may hold their citizenship indefinitely, unless they choose to voluntarily renounce it or it is revoked on valid legal grounds.
