How to Acquire Turkish Citizenship: All Routes for Foreigners

Foreigners can become Turkish citizens through five main routes: by birth, by descent, by marriage after three years, by five years of lawful residence (naturalization), or by investment starting at USD 400,000. Each path is governed by Turkish Citizenship Law No. 5901, and each carries its own conditions, timeline, and cost. This guide explains who qualifies for each route, how long it takes, what it costs beyond the investment, and how to avoid the mistakes that get applications refused or citizenship revoked.

The five routes at a glance

Before the detail, here is how the routes compare on the questions foreigners ask first: how much, how long, and what is required. Use this to find the path that fits your situation, then read the section that applies to you.

Timeframes are typical ranges, not guarantees; the actual time depends on your file, the route, and current caseloads at the population and citizenship authorities. Investment is the fastest path for most foreigners, while naturalization rewards those who have already built a life in Türkiye.

The legal framework: Turkish Citizenship Law No. 5901

Turkish citizenship is governed by Turkish Citizenship Law No. 5901 (Türk Vatandaşlığı Kanunu) and its implementing regulation, the Türk Vatandaşlığı Kanununun Uygulanmasına İlişkin Yönetmelik. The law recognizes two broad categories: citizenship acquired by birth and citizenship acquired after birth through naturalization, marriage, adoption, or exceptional grant.

Türkiye permits dual citizenship, so applicants generally do not have to renounce their existing nationality. Whether your home country lets you keep its passport is a separate question, decided by that country's own law, not by Turkish law.

Because eligibility turns on your individual facts, a Turkish lawyer should review your situation before you file. Speak to our team for a case-specific assessment.

Citizenship by birth: descent and place of birth

Citizenship by birth arises automatically by operation of law and is the most common way Turkish citizenship is acquired.

By descent (jus sanguinis)

A child is Turkish from the moment of birth if either the mother or the father is a Turkish citizen at that time, regardless of where the child is born. Where the parents are not married, descent through the father requires the legal bond of paternity to be established.

By place of birth (jus soli)

Türkiye does not grant citizenship simply for being born on its soil. However, a child born in Türkiye who cannot acquire any other nationality through their parents is recognized as Turkish to prevent statelessness. Foundlings found in Türkiye are likewise deemed born in Türkiye unless proven otherwise.

Citizenship by marriage to a Turkish citizen

Marriage to a Turkish national does not grant citizenship automatically, and it never has. Under Article 16 of Law No. 5901, a foreign spouse may apply only after the marriage has lasted at least three years and is still subsisting at the time of decision.

The conditions are:

• The marriage has continued for three years or more and remains valid;
• The couple live together as a family (the marriage must be real, not a paper arrangement);
• The applicant engages in no conduct incompatible with the unity of the marriage;
• The applicant poses no threat to national security or public order.

If the Turkish spouse dies after the application is lodged, the requirement to live together is excused. Authorities review marriage files closely and the Ministry keeps discretion to refuse where the marriage appears to exist only on paper.

Citizenship by naturalization (the 5-year residence route)

Ordinary naturalization under Article 11 of Law No. 5901 is the standard route for foreigners who have built a life in Türkiye. The principal conditions are:

• Five years of continuous, lawful residence in Türkiye immediately before applying, on a valid Turkish residence permit;
• An intention to settle in Türkiye, shown through conduct such as property, business, family, or investment ties;
• Good moral character and no criminal conduct that bars naturalization;
• Sufficient Turkish to communicate in daily life;
• No disease posing a danger to public health;
• Adequate income or a profession to support the applicant and dependents;
• No threat to national security or public order.

How much time abroad breaks the five years?

The five years must be continuous, and long absences can reset the clock. In practice, a single continuous absence of more than six months, or total absences exceeding about twelve months across the five-year period, can break the continuity. The authorities have discretion over how interrupted time is treated, so document the dates of every entry and exit.

Naturalization is discretionary. Meeting every condition makes you eligible to apply, but it does not by itself compel a grant; the Ministry still decides.

Exceptional citizenship by investment (Article 12)

The fastest route for many foreigners is exceptional citizenship under Article 12 of Law No. 5901, widely known as the Citizenship by Investment program. It requires no prior residence and no Turkish-language test, and the family can be included in a single application. The qualifying investments in force in 2026 are:

For the property purchase, valuation and title-deed (tapu) process, the value is fixed by the official valuation report, not the price you negotiate. The fixed-capital and job-creation routes usually run through a Turkish company, so they overlap with setting up a company in Türkiye. The job-creation route is confirmed by the Ministry of Labour and Social Security against SGK payroll records.

The investment is verified by the competent authority before the file is granted by Presidential decision. A spouse and children under 18 are naturalized on the same investment. Adult children (18 and over) and parents are not included and must qualify on their own basis. See our dedicated guide to the Turkish Citizenship by Investment program.

What citizenship by investment actually costs

The investment is the headline number, but it is not the whole bill. Budget for these additional costs so the figure you plan around is realistic:

• SPK valuation report for the real-estate route (a fixed professional fee per property);
• Title-deed transfer charge (tapu harcı) and the revolving-fund (döner sermaye) fee at the land registry;
• Government and application fees for the citizenship and passport files;
• Sworn translation, notarisation, apostille and legalisation of foreign documents (birth and marriage certificates, criminal-record extracts, passports);
• Legal fees for structuring the investment, due diligence, and managing the application end to end.

Losing or revoking citizenship — and how to avoid it

Citizenship obtained by investment is not beyond review. Under Law No. 5901, citizenship granted on the basis of false information or forged documents can be cancelled retroactively, and the cancellation can extend to family members who were included in the file.

This is not theoretical. In the 2025-2026 crackdown on real-estate fraud, Turkish authorities moved to revoke citizenship from hundreds of investors linked to sham sales and inflated valuations. The common threads were understated or fictitious property values, recycled properties, and collusion with brokers.

The way to protect your status is to keep the file clean from the start: a genuine market-value transaction, an honest SPK valuation, a property with a clean ownership history, and full compliance with the holding period. Articles 29 to 35 of Law No. 5901 also set out the narrower grounds on which citizenship can otherwise be lost; these rarely affect ordinary investors who follow the rules.

Other routes, the Blue Card, and family members

Law No. 5901 recognizes additional, narrower routes:

• By adoption — a minor adopted by a Turkish citizen may acquire citizenship if it does not threaten national security or public order;
• Reacquisition — former Turkish citizens who lost or renounced their nationality may apply to regain it under defined conditions.

The Blue Card (Mavi Kart)

The Blue Card is not citizenship. It is a status for people who gave up Turkish citizenship with official permission (and their descendants), preserving certain civil rights almost as if they were still citizens, such as the right to own property, inherit, reside, work, and run a business in Türkiye. It does not give a Turkish passport, voting rights, or the duties of citizenship. It matters most to people from countries that do not allow dual nationality and who therefore had to renounce their Turkish citizenship.

Which family members are covered?

On the investment route, only a spouse and children under 18 are naturalized on the same investment. Adult children and parents are not included automatically and must find their own qualifying route, whether residence, marriage, or their own investment.

The application process and documents

Across all routes, you will assemble a similar core file:

• Identity and civil-status documents (passport, birth certificate, and marriage certificate where relevant), usually apostilled or legalised and sworn-translated into Turkish;
• A clean criminal-record extract from your home country (and any country of long residence);
• Proof of the qualifying basis: the residence-permit history, the marriage record, or the investment confirmation;
• Photographs and the prescribed application forms.

Applications are filed with the population and citizenship authorities in Türkiye or, from abroad, through Turkish consulates. Investment files run faster because the qualifying basis is documented up front; marriage and naturalization files take longer because they depend on a record built over years.
