Acquiring Tajikistan dual citizenship is allowed under Tajik legislation, however Tajik law sets forth certain restrictions. Firstly, Tajikistan dual citizenship is determined under International Treaties signed by Tajikistan.

Moreover, Tajik citizen who has entered the military service in security agencies, justice bodies, law enforcement agencies or other state authorities in a foreign country, loses the nationality of the Republic of Tajikistan, unless otherwise provided in international treaties of Tajikistan.
