Bulgarian Citizenship: A Guide to Investment, Naturalization, Descent, and Marriage Routes
Global mobility and second citizenship are becoming mainstream options, and Bulgaria is drawing interest from people who want the advantages of EU membership. With its strategic location, growing economy, and several routes toward citizenship, Bulgaria offers opportunities for investors, entrepreneurs, and high-net-worth individuals.
This guide describes the different routes to Bulgarian citizenship: the investment-based route (now residence by investment followed by naturalization), naturalization, descent, and marriage. Whether you are an experienced global investor or exploring EU citizenship for the first time, Bulgaria may offer an option that suits your needs.
Introduction to Bulgarian Citizenship
Since joining the European Union in 2007, Bulgaria has become an appealing country for people seeking European citizenship. Its rich history, multi-ethnic culture, and developing economy offer advantages that attract prospective citizens.
As citizens of a full EU member state, Bulgarian citizens have the right to reside, work, and travel in all 27 EU countries. Bulgaria has also been a full member of the Schengen Area since January 1, 2025. Bulgarian citizenship gives access to healthcare and education systems across the EU, as well as visa-free travel to many destinations, including the United Kingdom and Canada (electronic travel authorization may be required).
With its relatively low cost of living and favorable tax policy, Bulgaria is an attractive base for international investors and high-net-worth individuals. The country applies a flat 10% personal income tax, one of the lowest rates in the EU. Together with a dynamic real estate market and developing economic sectors, this has made Bulgaria an increasingly valuable entry point to the European market.
The following sections discuss the ways Bulgarian citizenship can be acquired to help you assess which route may be most suitable for your circumstances and objectives.
Bulgarian Citizenship by Investment (Closed in 2022)
Overview of the Program
Bulgaria previously offered a citizenship-by-investment (CBI) route. In March 2022, the Bulgarian Parliament amended the Bulgarian Citizenship Act and abolished it, so direct citizenship in exchange for investment is no longer available to new applicants.
Bulgaria still offers residence by investment. Under the Foreigners in the Republic of Bulgaria Act, qualifying investors may receive permanent residence. After holding permanent residence for at least five years, they may apply for citizenship through standard naturalization, provided they meet all the requirements, including Bulgarian language proficiency.
Bulgaria’s residence-by-investment route remains of interest because it provides permanent residence from the outset, which can allow investors to continue managing their international business interests while working toward eligibility for naturalization.
Investment Options
Following Bulgaria’s adoption of the euro on January 1, 2026, the statutory thresholds (set in Bulgarian leva) convert at the fixed rate of BGN 1.95583 per euro. The main options include:
- Licensed investment funds: An investment of BGN 1,000,000 (approximately EUR 511,300) in collective investment schemes or alternative investment funds licensed in Bulgaria and meeting the statutory criteria. The investment must be held for five years. The former option of investing in Bulgarian government bonds is no longer available.
- Higher-threshold options: An investment of BGN 2,000,000 (approximately EUR 1,022,600) in shares or bonds of Bulgarian companies traded on a Bulgarian regulated market, or in a company carrying out a certified priority investment project. These options also lead to permanent residence.
Fast-Track Option
The former fast-track option, which allowed investors who doubled their investment to apply for citizenship after one year of permanent residence, was abolished together with the CBI route in 2022. Investing a higher amount no longer shortens the path to citizenship. Applicants in all investment categories must meet the standard naturalization requirements.
Benefits of Bulgarian Citizenship
Bulgarian citizenship obtained after residence by investment and naturalization offers several advantages:
- EU citizenship: Bulgarian citizens have the right to live and work in any of the 27 EU member states, with access to a wide range of economic, cultural, and social opportunities.
- Visa-free travel: Bulgarian citizens can travel visa-free or with visa on arrival to many destinations, including the Schengen Area, the United Kingdom, and Canada (electronic travel authorization may be required).
- Low taxation: Bulgaria applies a flat 10% personal income tax, among the lowest in Europe, which can be attractive for entrepreneurs and investors.
- Family inclusion: A spouse and minor children may obtain permanent residence together with the investor. Each family member must then meet the applicable requirements to apply for citizenship.
Eligibility Requirements
The residence-by-investment route and later naturalization come with eligibility requirements, including:
- Clean criminal record: Applicants should not have criminal convictions in Bulgaria or their home country.
- Legal source of funds: Applicants must prove that the funds used for the investment come from legal sources.
- Language requirement: Bulgarian language proficiency is required when applying for citizenship by naturalization.
- Physical presence: Current rules for investor permanent residence do not set a minimum stay. However, a bill tabled in the National Assembly in July 2026 proposes withdrawing permanent residence from holders who spend less than six months and one day in Bulgaria in a calendar year. Applicants should check the status of this proposal before applying.
Citizenship by Naturalization
Eligibility
Naturalization is the second route to Bulgarian citizenship. It is intended for foreign nationals who have lived in Bulgaria on a long-term basis. Applicants must be at least 18 years old and have held a permanent or long-term residence permit for at least five years. They must also demonstrate Bulgarian language proficiency and have an income or occupation that allows them to support themselves in Bulgaria.
Procedure
Applying for citizenship through naturalization typically involves the following steps:
- Residence: The applicant must have held a permanent or long-term residence permit for at least five years before applying.
- Language exam: Applicants must pass a Bulgarian language exam, unless they are exempt (for example, because they studied at a Bulgarian school or university).
- Clean criminal record: Applicants must provide proof of a clean criminal record.
- Renunciation of previous citizenship: Applicants generally must give up their previous citizenship. Exemptions apply to certain groups, including EU, EEA, and Swiss citizens.
Advantages and Challenges
Naturalization provides a route to citizenship, but it comes with challenges. The five-year residence period requires a long-term commitment to living in Bulgaria. The language exam can also be a barrier for applicants unfamiliar with the Bulgarian language.
Even so, naturalization is an affordable and accessible option for people who already live in Bulgaria and have integrated into society.
Citizenship by Descent
Eligibility
Bulgaria grants citizenship to people who can prove Bulgarian origin. A child born to at least one Bulgarian parent is a Bulgarian citizen by birth. People with Bulgarian ancestry through their parents, grandparents, or great-grandparents may be eligible for citizenship on the basis of Bulgarian origin. This route is often the most affordable, as it does not require an investment.
Process
The process of acquiring Bulgarian citizenship by descent includes:
- Proof of ancestry: Applicants must prove their Bulgarian origin through birth certificates, family records, or other official documents accepted as adequate proof.
- Application submission: Once all necessary documents are gathered, the application is submitted to the competent Bulgarian authorities.
- Processing time: This route is usually straightforward, but processing times depend on the availability and quality of the documentation.
Key Benefit
For those who can prove Bulgarian origin, this is often the most accessible and affordable route to citizenship. Unlike residence by investment or naturalization, citizenship by descent does not require an investment, prior residence, language proficiency, or renunciation of existing citizenship.
Citizenship by Marriage
Eligibility
Marriage to a Bulgarian citizen does not provide immediate eligibility for citizenship. A foreign national may apply after being legally married to a Bulgarian citizen for at least three years and holding a permanent or long-term residence permit in Bulgaria for at least three years.
Application Process
To apply for Bulgarian citizenship through marriage, the typical steps are:
- Marriage and residence: The applicant must have been legally married to a Bulgarian citizen for at least three years, remain married at the time of application, and have held a permanent or long-term residence permit for at least three years.
- Application submission: Once the marriage and residence requirements are met, the applicant may submit an application to the Bulgarian authorities.
- Genuine relationship: The marriage must be legally valid and genuine. The authorities may verify the relationship before deciding on the application.
- Language proficiency: Applicants must also meet the Bulgarian language requirement that applies to naturalization.
Residency and Citizenship
Marriage can support a citizenship application, but applicants must first obtain permanent or long-term residence and then apply for naturalization on a reduced timeline. This is not one of the fastest routes to Bulgarian citizenship, but it can suit people with personal or family ties to Bulgaria.
Special Considerations for Bulgarian Citizenship
Dual Citizenship
Bulgaria allows dual citizenship in certain cases. Bulgarian citizens by birth, citizens of EU and EEA countries and Switzerland, citizens of countries with reciprocity agreements with Bulgaria, spouses of Bulgarian citizens, and people who prove Bulgarian origin are generally not required to renounce their existing nationality. Other applicants for naturalization are usually required to give up their previous citizenship. This is an important factor for anyone who wants to access EU membership benefits while keeping their original citizenship.
Physical Residency Requirements
Investors must maintain their qualifying investment for five years and hold permanent residence for at least five years before applying for citizenship. Naturalization and citizenship through marriage also require applicants to hold residence in Bulgaria for a specified number of years before applying. As noted above, a July 2026 bill proposes a minimum presence requirement for all permanent residence holders, so applicants should monitor its progress.
Processing Time
Since the fast-track option was abolished, there is no accelerated investment route to citizenship. Investors typically become eligible to apply for naturalization after five years of permanent residence, and processing of the citizenship application takes additional time. Naturalization and marriage routes also require several years of residence before an application can be filed.
Citizenship Pathway Comparisons
Residence by Investment vs. Naturalization
- Residence by investment: Provides permanent residence from the outset in return for a qualifying investment. Citizenship is then available through naturalization after five years, subject to the language and other requirements.
- Naturalization (general route): Requires five years of permanent or long-term residence obtained on another basis, basic Bulgarian language proficiency, and integration into Bulgarian society. It is best suited to people who are already long-term residents.
Residence by Investment vs. Citizenship by Descent
- Citizenship by descent: A more affordable and often simpler route, but limited to people who can prove Bulgarian origin.
- Residence by investment: Available to qualified non-EU investors regardless of ancestry, but it leads to citizenship only through naturalization.
Marriage vs. Residence by Investment
- Citizenship through marriage: Requires three years of marriage, three years of permanent or long-term residence, and proof of a genuine relationship.
- Residence by investment: Requires a qualifying financial investment and five years of permanent residence before a citizenship application. Applicants with family ties to Bulgaria may find the marriage route more suitable, while residence by investment may offer more flexibility for others.
Conclusion: Finding Your Path to Bulgarian Citizenship
Bulgaria offers several paths to citizenship, which makes it a destination of interest for international investors and people seeking EU citizenship. Although the citizenship-by-investment route closed in 2022, residence by investment remains an option for high-net-worth individuals who want EU permanent residence, access to the EU market, and a potential path to citizenship through naturalization.
For people of Bulgarian origin, citizenship by descent is usually the most straightforward and affordable route. Naturalization and marriage are further options for long-term residents and people with family ties to Bulgaria.
The right route depends on your long-term goals, investment capacity, and personal circumstances. It is recommended to consult legal professionals experienced in Bulgarian citizenship matters for advice on your specific case. Researching your options carefully will help you find the route that best matches your global mobility and investment goals.
