How to obtain Bulgarian citizenship in 2026 — naturalisation, marriage & descent

Bulgarian citizenship grants EU rights, visa-free travel, political participation and a pathway to full integration in Europe. In 2026, applicants can qualify through naturalisation, marriage to a Bulgarian citizen, descent, birth, adoption, the option procedure, humanitarian grounds and other exceptional cases. If you still hold only residence status, first review our Bulgaria residence guide to align your path from residence to nationality.

Key terms

Naturalisation: acquisition of Bulgarian citizenship after long-term residence, language skills and clean record.

Option procedure: simplified route for certain groups, such as those with Bulgarian parents or long-term residents born in Bulgaria.

Ministry of Justice: central authority processing citizenship applications.

State Agency for National Security (SANS): body verifying security and background compliance.

Civic integration: proof of Bulgarian language and cultural knowledge required for naturalisation.

Dual nationality: Bulgaria generally allows it, especially by descent and marriage.

Permanent residence: status usually required before applying for citizenship.

Citizenship types

• Naturalisation: Foreigners may apply after at least 5 years of permanent residence. Requirements include Bulgarian language knowledge (usually B1), stable legal stay, clean criminal record and loyalty to the Constitution. Applications undergo SANS checks and Ministry of Justice review. Successful candidates attend a ceremony where they take an oath of allegiance.
• Marriage: Spouses of Bulgarian citizens can apply after 3 years of marriage and residence together in Bulgaria. Proof of genuine cohabitation is essential: shared address registration, joint accounts or children are often checked. Divorce before approval terminates eligibility.
• Descent (by blood): Children of Bulgarian citizens acquire nationality automatically at birth. Adults can reclaim nationality by presenting genealogical proof of Bulgarian parents or grandparents. Documents may include archived birth records, church registries or municipal archives. Descent-based claims are subject to strict scrutiny to prevent fraud.
• Birth in Bulgaria: Bulgaria follows limited jus soli. Stateless children or those with unknown parents born in Bulgaria may be granted nationality. This provision ensures no child born on Bulgarian soil remains stateless.
• Adoption: Minors adopted by Bulgarian citizens acquire citizenship automatically if adoption is recognised by Bulgarian courts. The rule applies only to full adoption cases and does not extend to adult adoptees.
• Military service / merit: Citizenship may be granted exceptionally to foreigners who rendered outstanding service to Bulgaria, for example through military participation, scientific breakthroughs or cultural achievements. This route is discretionary and rare.
• Investment: Bulgaria abolished its direct citizenship-by-investment scheme in 2022. Today investors must follow the regular track: residence → permanent residence → naturalisation. Authorities prioritise transparent investment that contributes jobs and growth.
• Humanitarian grounds: In rare cases, citizenship can be awarded for humanitarian reasons, such as to stateless individuals, long-term refugees or other exceptional humanitarian cases. Decisions are discretionary and require presidential decree.

Routes & timelines

Step-by-step

1. Check eligibility: confirm years of permanent residence, marriage duration, or descent records.
2. Prepare integration proofs: pass Bulgarian language test and prepare Constitution knowledge.
3. Collect documents: passports, residence cards, genealogical records, birth and marriage certificates, criminal record certificates from all countries of residence.
4. Submit application: file at the Ministry of Justice in Sofia, supported by municipality records.
5. Background check: SANS verifies security and law compliance.
6. Decision & oath: approved applicants attend an oath ceremony and receive a certificate of Bulgarian nationality.

Documents

Applicants need a valid passport, permanent residence card, birth/marriage certificates, genealogical records, criminal record certificates, proof of Bulgarian language skills, and integration evidence. All foreign documents must be legalised and translated into Bulgarian — use certified translations to avoid rejection.

Costs

Typical expenses include government application fees, integration/language exam charges, translations/legalisation and optional legal representation. While exact sums vary, Bulgaria remains more affordable than many EU states. For global comparisons, check our Residency & Citizenship hub.

Integration

Civic integration for Bulgarian citizenship involves more than language exams. Authorities look at:

• Bulgarian language proficiency at B1 or equivalent certification.
• Knowledge of Bulgarian Constitution, history and social norms, tested during interviews.
• Demonstrated integration through work, education, tax compliance or family ties.

Applicants who fail to show integration may face delays or rejection, even if residence requirements are met.

What changed in 2026

In 2026 Bulgaria introduced clearer rules on integration testing, launched an online submission portal for Ministry of Justice applications, and tightened scrutiny of descent claims to prevent misuse. Dual nationality policy remains unchanged, still allowing wide eligibility compared to other EU states.

Did you know?

Bulgaria is among the few EU countries where dual citizenship is permitted broadly, especially through descent and marriage, making it attractive for diaspora communities worldwide.

Common mistakes

• Confusing permanent residence with eligibility for citizenship — naturalisation requires a separate application.
• Filing descent claims without complete genealogical evidence — partial archives are insufficient.
• Assuming marriage alone suffices — integration and cohabitation proofs are equally important.
• Submitting untranslated or unlegalised documents, causing immediate rejection.
• Missing deadlines for additional requests from the Ministry of Justice.
• Neglecting language and integration preparation, which leads to delays or refusal.

FAQ

Expert opinion

Bulgarian citizenship is realistic for many foreigners, but success depends on proving integration, providing full genealogical evidence and managing residence timelines carefully. Preparation reduces risks of rejection.
