Is Uzbekistan dual citizenship?

No, Uzbekistan does not recognize dual citizenship. A person who possesses two passports from separate nations with matching agreements is said to have dual citizenship. A dual citizen is still entitled to all rights and obligations in both nations. For instance, Russia and Tajikistan have such an arrangement. This practice is illegal and does not exist in Uzbekistan.

A person who holds a passport from another nation yet is recognized as a citizen of each state is said to have second citizenship. In other words, while it's not against the law, your passport will only be accepted as proof of Uzbekistani citizenship.

That is, unless he has formally renounced his citizenship and received a personal signature from the nation's president, a citizen of Uzbekistan who also holds citizenship in another state cannot avoid fulfilling his obligations or be freed from duty.

Getting a second citizenship might make you lose your Uzbek citizenship. Since you already have citizenship in another state, you may be deported from the nation and stripped of your citizenship, to put it roughly. Furthermore, there will be no way for you to affect it.
