Article 10 of the Law “On Citizenship of Turkmenistan” defines three models for acquisition of citizenship namely: by birth (ius ildarius/sanguinis), through naturalisation (admission to the citizenship), and by restoration of the citizenship. Article 10 also allows the acquisition of citizenship in accordance with terms and conditions of international agreements of Turkmenistan.
Currently there are no such agreements in force. The treaty between the Russian Federation and Turkmenistan on the settlement of dual citizenship issues (Ashgabat, 23 December 1993; ratified by the Russian Federation on 25 November 1994) was in effect until 18 May 2015. For said Treaty, the validity term was five years with automatic extension for subsequent five-year periods. However, on the initiative of Turkmenistan it was not extended.
Article 5 of the Law On Citizenship provides that Turkmenistan does not recognize other citizenships of its citizens. However, acquisition of a citizenship of another state does not entail the loss of citizenship of Turkmenistan. Turkmenistan would not acknowledge the second citizenship of its citizens unless the person who acquired the second citizenship renounces its original citizenship.
A person is deemed to be a Turkmen national regardless of his/her second citizenship unless the original (Turkmen) citizenship is voluntarily renounced by the person who acquired the second citizenship or it has been repealed by Turkmen authorities.
