In accordance with the citizenship act, Russian citizenship could be acquired: by birth; as a result of admission to the citizenship of the Russian Federation; as a result of restoration in the citizenship of the Russian Federation; and on other grounds provided by the Federal Law or international treaty of the Russian Federation.
In accordance with article 62 of the Constitution of the Russian Federation and Article 6 of the Citizenship Act, dual citizenship is allowed only if there is a treaty on recognition of dual citizenship between Russia and a foreign state. If a Russian citizen acquires a foreign citizenship, with which no relevant international treaty has been signed, he is considered to have acquired a second (as opposed to dual) citizenship.
Acquisition of a second citizenship by a Russian citizen does not mean cessation of his Russian citizenship nor does it diminish his/her rights and freedoms or insinuate release from the obligations resultant from the Russian citizenship, unless otherwise provided for by a federal law or an international treaty of the Russian Federation (Article 62(2) of the Constitution of the Russian Federation).
A Russian citizen (excluding those residing abroad) who has another citizenship shall submit a written notification of the second citizenship with the competent authority of the Russian Ministry of the Interior at the place of his residence within 60 days. A Russian citizen who fails to submit such notification within the established time limit due to his stay abroad shall submit it within 30 days of entry in the Russian Federation. Delay or failure in submission of the notification or submission of incomplete data to be contained therein is punishable and entails responsibility established by laws and regulations of the Russian Federation.
The law provides that an individual cannot access government service if he/she has a citizenship of another state, unless otherwise provided by a treaty of the Russian Federation. An individual may not be elected as a member of the Federation Council or a deputy of State Duma; or be a founder (participant) or constitute the editorial office of a mass media or broadcasting entity; and may not own, manage or control over 20% shares (interest) in the authorized capital such entity if he/she has citizenship of another state.
