Article 12 of the Law “On Citizenship of the Republic of Uzbekistan” defines four models for acquisition of citizenship:
Article 10 of the Law On Citizenship provides that Uzbekistan does not recognize Uzbekistan dual citizenship of its citizens. A person is deemed to be an Uzbek national regardless of his/her second citizenship, unless the person acquiring the second citizenship voluntarily renounces the original (Uzbek) citizenship or otherwise loses the citizenship.
According to the amendments made in 2016 to the article 21 of the Law of the Republic of Uzbekistan “On Citizenship of the Republic of Uzbekistan”, acquisition of a citizenship of another state causes the loss of the citizenship of the Republic of Uzbekistan. The law obliges a person that accepted the citizenship of a foreign state to report this fact to the internal affairs bodies or consular offices of the Republic of Uzbekistan abroad within 30 days. The loss of the citizenship is documented by a relevant decree of the President of Uzbekistan.
The amended law also states that an adopted child who is a foreign citizen, can become a citizen of the Republic of Uzbekistan only after withdrawal from the citizenship of another state.
