Dual Citizenship Between the USA and Turkey: Rules Explained
Yes, both the United States and Turkey allow dual citizenship, so an American can become a Turkish citizen without giving up a U.S. passport. This guide explains the Turkish legal framework under Law No. 5901, the routes to citizenship (including the 2026 investment thresholds), and the obligations each nationality carries, from military service to taxes to which passport to show at the border.
Does the US allow dual citizenship with Turkey?
Yes. Both countries accept dual nationality, so you can lawfully hold a U.S. passport and a Turkish passport at the same time.
Turkey has permitted multiple nationality since 1981, and the rule is set out in the current Turkish Citizenship Law No. 5901 (Türk Vatandaşlığı Kanunu, adopted 2009). A foreigner who acquires Turkish citizenship is generally not required to give up their original nationality, and a Turkish citizen who naturalizes abroad does not automatically lose Turkish status.
The United States takes the same permissive line. U.S. law does not force a naturalized foreigner, or a U.S. citizen who acquires another nationality, to choose one country. Because both systems accept the arrangement, dual status is not a loophole; it is the ordinary, lawful position.
One thing to keep in mind from the start: holding both nationalities does not erase the duties of either. Each country treats you as a full citizen and expects you to comply with its laws, a point that matters most for military service and tax, covered below.
The Turkish legal framework: Law No. 5901
Turkish nationality is governed primarily by Law No. 5901 and its implementing regulation. For foreigners, four routes matter:
- Citizenship by birth (descent): A child born to at least one Turkish parent is Turkish by descent, wherever the child is born. This is how most Americans of Turkish heritage already hold dual status, including U.S.-born children of a Turkish parent (see the descent section below).
- Ordinary naturalization (Art. 11): Generally requires lawful, continuous residence in Turkey for five years, intent to settle, good character, sufficient income and basic Turkish, subject to discretionary approval.
- Naturalization by marriage (Art. 16): Available after three years of marriage to a Turkish citizen, where the marriage subsists and the couple genuinely lives together as a family.
- Exceptional / investment-based citizenship (Art. 12): Granted to qualifying investors. The grant authority used to sit with the Council of Ministers; since the move to a presidential system in 2018 it sits with the Presidency. Investment thresholds are fixed by Presidential regulation and are set out in the next section.
The residence stage that precedes most applications sits in a separate statute, the Law on Foreigners and International Protection No. 6458. For a fuller map of every entry point, see our guide to all the ways to obtain Turkish citizenship, and our residence permit and immigration team handles the permit stage.
Turkish citizenship by investment: 2026 thresholds
The investment route is usually the fastest for Americans with no Turkish family ties. It runs under the exceptional-naturalization provisions of Law 5901, and the qualifying figures are fixed by Presidential regulation. The real-estate threshold rose from USD 250,000 to USD 400,000 in 2022; the non-real-estate routes sit higher, at USD 500,000.
Here are the current options side by side:
| Route | Minimum (2026) | Hold period | Confirmed by |
|---|---|---|---|
| Real estate | USD 400,000 | 3 years (no-sale undertaking) | Land Registry / valuation report |
| Bank deposit | USD 500,000 | 3 years (funds blocked) | BDDK / the bank |
| Fixed capital investment | USD 500,000 | 3 years | Ministry of Industry and Technology |
| Government bonds | USD 500,000 | 3 years | Ministry of Treasury and Finance |
| Job creation | 50 employees | maintained 3 years | Ministry of Labour (SGK records) |
A few practical notes. The 50-employee route counts SGK-registered Turkish citizens in full-time work, kept on the books for three years. The real-estate route needs a valuation report and usually a sworn translator and notary; our property purchase and conveyancing team handles those steps. For the deposit option, see our guide to citizenship by bank deposit, and for the route in general, citizenship through investment.
The residence permit step before citizenship
Since 2024, the investment route runs through a residence permit first. The investor takes a short-term residence permit under Article 31(1)(j) of Law No. 6458, and the citizenship application is filed on top of it. There is no minimum-stay requirement for this permit; it is a procedural gateway, not a relocation.
This single step replaces the older practice of filing for citizenship directly. It is paperwork-heavy but routine when handled correctly; the documents (apostilled, sworn-translated) are the same set you will reuse for the citizenship file. Our immigration team prepares both stages together so they do not stall each other.
Citizenship by descent: are your children Turkish?
This is one of the most common questions Americans ask, and the answer is usually yes. Under Law 5901, a child with at least one Turkish parent is Turkish by descent from birth, regardless of where the child is born. A child born in the United States to a Turkish mother or father is therefore generally a Turkish citizen automatically, even if you never registered them.
What is automatic in law still needs paperwork in practice. To get a Turkish ID number, passport and entry in the population register (nüfus), the birth must be reported to a Turkish consulate or the nüfus office, with the U.S. birth certificate apostilled and sworn-translated. Until that is done, the child is Turkish on paper but cannot yet use the status.
Turkish military service for dual citizens
Military service is the single most-searched worry for male U.S.-Turkish dual nationals, so it deserves a clear answer. Male Turkish citizens are subject to compulsory military service, and acquiring Turkish citizenship as an adult does not, by itself, switch this off. Living abroad does not automatically exempt you either. But there are well-established ways to resolve the obligation without serving on the ground.
Dövizle askerlik (the foreign-residence option)
If you have lived abroad for at least three consecutive years (1,095 days) with evidence of work or study, you can generally settle the obligation through dövizle askerlik: a set payment in foreign currency plus a short remote training, rather than active service. This is the route most U.S.-based dual nationals use.
Bedelli (the paid-exemption option)
For those who do not meet the foreign-residence test, the bedelli paid-exemption scheme lets eligible men discharge the obligation by paying a fee and completing a brief training period. Eligibility rules and the fee are set by law and reviewed periodically.
Service completed abroad
If you already completed equivalent military service in another country, that can count toward resolving the Turkish obligation. Documentation is key.
Tax: do you still pay US tax if you become Turkish?
Yes. The United States taxes its citizens on worldwide income wherever they live, so becoming Turkish does not end your U.S. filing. You keep filing U.S. returns and, where the thresholds are met, foreign-account reports. Turkey taxes residents on worldwide income and non-residents on Turkish-source income.
Here is the practical picture for a U.S.-Turkish dual citizen:
| Obligation | United States | Turkey |
|---|---|---|
| Income tax basis | Citizenship (worldwide income) | Residence (worldwide if resident) |
| Annual return | Yes, even if living in Turkey | Yes, if Turkish tax-resident |
| Foreign-account report | FBAR if accounts together exceed USD 10,000 | n/a |
| Asset report | FATCA Form 8938 above set thresholds | n/a |
FBAR (FinCEN Form 114) is triggered when your foreign financial accounts together top USD 10,000 at any point in the year; it is a report, not a tax. FATCA (Form 8938) starts higher and the threshold varies with filing status and where you live. The U.S.-Turkey double taxation treaty (signed 1996, in force since 1997) reduces double taxation but does not remove the duty to file in both systems.
Passports, records and everyday obligations
A few everyday rules keep dual life smooth.
Use the right passport at each border
Turkey expects its citizens to enter and leave Turkey on a Turkish passport; the U.S. expects its citizens to enter the United States on a U.S. passport. Carry both and present the correct one at each border. A side benefit of the Turkish passport is broad visa-free travel on a Turkish passport.
Keep your names and dates consistent
A frequent, avoidable snag is a mismatch between U.S. and Turkish records, a different spelling, a transliterated name, or a birth-date format difference. The nüfus and border systems read your Turkish details; if they do not match your U.S. documents, expect questions. Fix discrepancies through the population office early.
Consular help is limited inside Turkey
While you are in Turkey, a U.S.-Turkish dual citizen is treated as Turkish. That can limit the help the U.S. embassy can give in matters such as detention or family disputes, because Turkey does not recognize the other nationality on its own soil.
Losing or renouncing Turkish citizenship
Law 5901 also governs loss of nationality. Turkish citizenship can be lost by renunciation with official permission, or revoked in narrow cases defined by law (for example, naturalization obtained by fraud). A Turkish citizen who renounces with permission may apply for the Blue Card (Mavi Kart), which preserves most civil rights in Turkey, property ownership, residence, inheritance, without full citizenship.
Know what the Blue Card does not give: it is not a Turkish passport, it does not carry voting rights, and it does not, on its own, settle a male holder's military position. Renouncing U.S. citizenship is a separate, far more consequential step under U.S. law before a consular officer, and for higher-net-worth individuals it can trigger the U.S. exit tax for "covered expatriates."
Most dual citizens never need to renounce either nationality; the two are designed to coexist. Renunciation is a planning decision, not a default, and it is worth legal advice on both sides before you act.

Frequently asked questions
Does the US allow dual citizenship with Turkey?
Yes. Both countries permit dual nationality. Under Turkish Citizenship Law No. 5901 a foreigner who naturalizes is not required to renounce their original nationality, and U.S. law tolerates holding a second passport. You can hold a U.S. and a Turkish passport at the same time.
How much do I need to invest for Turkish citizenship in 2026?
The real-estate route requires at least USD 400,000 held for three years. The non-real-estate routes (bank deposit, fixed capital, government bonds) require USD 500,000 held for three years, and the job-creation route requires employing 50 SGK-registered Turkish workers for three years. Confirm the figure on your filing date, as thresholds are set by regulation.
Will I have to do Turkish military service if I become a dual citizen?
Male Turkish citizens are subject to compulsory service, and acquiring citizenship as an adult does not switch this off automatically. If you have lived abroad for at least three consecutive years you can usually settle it through dövizle askerlik (a foreign-currency payment plus short training); otherwise the bedelli paid-exemption scheme or service completed abroad may resolve it. Check your position before travelling to Turkey.
Is my child Turkish if one parent is Turkish?
Generally yes. Under Law 5901 a child with at least one Turkish parent is Turkish by descent from birth, wherever the child is born, including in the United States. The status is automatic, but you must register the birth with a Turkish consulate or population office, with an apostilled and translated birth certificate, before the child gets a Turkish ID and passport.
Do I still pay US taxes if I become Turkish?
Yes. The United States taxes citizens on worldwide income wherever they live, so you keep filing U.S. returns, plus FBAR if your foreign accounts together exceed USD 10,000 and FATCA Form 8938 above its thresholds. Turkey taxes residents on worldwide income. The U.S.-Turkey tax treaty (in force since 1997) reduces double taxation but does not end the duty to file in both systems.
Which passport should a dual citizen use at the border?
Enter and leave Turkey on your Turkish passport and enter the United States on your U.S. passport. Carry both and present the correct one at each border. Keep the name and birth-date details on your Turkish records consistent with your U.S. documents to avoid questions.
