Dual nationality, notification and military service
Türkiye permits dual nationality and does not require you to renounce your existing citizenship. It does require you to notify the authorities of a foreign nationality acquired or held. Whether your own state allows you to keep its nationality after naturalising is a question for that state's law, to be settled before you apply. For male citizens, Turkish nationality carries a military service obligation, with defined mechanisms for those resident abroad.

Permitted, and declared
Turkish law does not treat a second nationality as a problem. What it requires is that the authorities know about it: a citizen who acquires a foreign nationality, or a foreigner who becomes Turkish while retaining their own, is under a notification obligation. It is a small step that is frequently overlooked, and the consequence of overlooking it is inconsistency between records that surfaces at the worst moment — a passport application, an inheritance, a property transfer.
What changes practically
| Item | Effect |
|---|---|
| Turkish identity number | Issued on acquisition; required for banking, property, health, everything administrative |
| Passport | Issued on the same terms as any citizen; see the firm's note on the Turkish passport |
| Property | Owned free of the restrictions that apply to foreigners, including zone restrictions |
| Residence permits | No longer needed — and a held permit lapses on acquisition |
| Entry and exit | Turkish citizens enter and leave on the Turkish passport or identity card |
| Consular protection | Türkiye will generally not extend consular protection against Türkiye |
Military service
Turkish nationality carries a military service obligation for male citizens. For dual nationals resident abroad the position is governed by its own legislation and includes defined mechanisms — deferral tied to residence and work abroad, and a paid-service mechanism whose terms and figures are set by law and have changed several times. Exemptions exist on health grounds and in defined circumstances.
What matters in planning terms is that this is the single obligation most likely to be discovered late by a family that acquired citizenship for other reasons. The firm's guidance on military service for dual citizens sets out the current mechanisms, and its note on Blue Card holders and conscription covers the position of descendants of former citizens.
Losing it
Citizenship acquired after birth can be lost in defined circumstances — most relevantly, it may be annulled where it was acquired by false statement or by concealing something material to the acquisition. That is a finding about the original application rather than about later conduct, and it can surface years afterwards when an unrelated file brings the papers back into view. See refusals and codes for the challenge machinery.
Children
Children of a Turkish citizen are Turkish by descent, wherever born — see citizenship by birth and descent. That means a family acquiring citizenship is not making a decision only for the adults: the status passes down automatically thereafter, with everything attached to it. It is a good reason to think about the military-service question a generation ahead rather than one application at a time.
Frequently asked questions
Does Türkiye allow dual citizenship?
Yes, and it does not require you to renounce your existing nationality. It does require notification of a foreign nationality acquired or held.
Will I lose my current citizenship if I become Turkish?
Not because of Turkish law. Whether you keep it is decided by your own state, and the answer ranges from freely permitted to automatic loss. Confirm it before you apply.
Do dual citizens have to do Turkish military service?
Male Turkish citizens carry the obligation. For dual nationals resident abroad there are defined mechanisms including deferral and a paid-service option, and exemptions exist in specified circumstances. The terms are set by legislation and have changed more than once.
What happens to my residence permit when I become a citizen?
It is no longer needed and lapses. Everything it enabled — residence, work, property without the foreigner restrictions — follows from the citizenship instead.
