In Ukraine, the legal framework regarding dual citizenship is determined by the following sources:

Constitution of Ukraine (1996, revised 2022): Citizenship and fundamental rights, state policies on single or multiple citizenship.
Ukrainian Citizenship Law (2001, revised 2025–2026): A law defining dual citizenship and exceptional circumstances.
Presidential Decrees and Consular Regulations: These apply to passport, identity card, and registration processes.

With the 2026 reform, Ukraine officially accepted dual citizenship with certain countries, but restrictions on dual citizenship with “aggressor states” remained in place. (dia.dp.gov.ua)

2. The Principle of Dual Citizenship

The law regarding dual citizenship in Ukraine is based on the following principles:

Official Recognition: After 2026, second or third citizenship obtained with certain countries will be officially recognized.
Internal Status: Dual citizens residing in Ukraine are considered solely Ukrainian citizens. This means their other citizenships are not legally recognized by the state.
Aggressor State Restriction: Dual citizenship is prohibited with Russia and some other countries; this is enforced on grounds of national security.

In this context, dual citizenship is considered both an international right and a right limited by state policy .

Documents related to birth, adoption, or immigration are officially registered at the consulate.

A Ukrainian father wants to perform jus sanguinis on his child born in Russia.
Since Russia is considered an "aggressor state," the child's Ukrainian citizenship is at risk.

If the second citizenship was obtained from friendly countries, it is officially recognized by Ukraine.
