Turkish citizenship may be acquired by birth or by decision of the authorities. For foreign nationals three routes matter in practice: investment, marriage and ordinary naturalisation.
Citizenship by Investment
The exceptional route allows citizenship where a qualifying investment is made and maintained. Recognised forms include the purchase of real estate, a fixed capital investment, a deposit held in a Turkish bank, and the creation of employment for a specified number of workers.
Two conditions are constant across all forms. First, the investment must be maintained for three years, and this undertaking is annotated on the title deed or the relevant record. Second, the qualifying value is certified by an official valuation report, not by the declared sale price.
The monetary thresholds are set by regulation and have changed several times. They are deliberately not reproduced here; a figure quoted on a website ages badly and an outdated threshold is worse than none. Current thresholds should be confirmed before any commitment is made.
Citizenship by Marriage
Marriage to a Turkish citizen does not confer citizenship automatically. An application may be made after the marriage has subsisted for three years, and the marriage must still be in existence when the decision is taken.
The authorities examine whether the couple live together as a family. A marriage found to have been entered into for the purpose of acquiring citizenship is refused, and citizenship already granted on that basis may be annulled.
Where the Turkish spouse dies after the application, the requirement of an existing marriage is assessed differently; the surviving spouse is not automatically disqualified.
Ordinary Naturalisation
The general route requires, among other conditions, five years of uninterrupted residence in Turkey, an intention to settle, adequate command of Turkish, sufficient income or occupation to support oneself and dependants, and the absence of circumstances constituting an obstacle in terms of public order or national security.
Absences from Turkey are deducted from the residence period. Time spent under certain permit types may not count towards it at all, which is the point most often misunderstood — holding a residence permit for five years is not the same as satisfying the five-year residence requirement.
Procedure and Refusals
Applications are made to the provincial directorate of civil registration or, for applicants abroad, through a Turkish consulate. The file passes through the provincial authority to the Directorate General of Population and Citizenship Affairs; the final decision rests with the President.
A refusal is an administrative act. It may be challenged before the administrative courts within the statutory time limit, which runs from notification of the decision. Reasons must be examined before an action is brought; many refusals turn on a documentary deficiency that can be cured by a fresh application rather than litigation.
Frequently Asked Questions
No. The property must meet the qualifying value certified by an official valuation report, and an undertaking not to sell for three years is annotated on the title deed.
There is no guaranteed period. Processing depends on the route, the completeness of the file and the workload of the authorities.
Where it is established that the marriage was entered into for the purpose of acquiring citizenship, annulment may follow.
Turkish law does not require renunciation. Whether your own country permits dual citizenship is a question of that country's law.
