Does Ukraine allow dual citizenship? The six cases in the 2026 law and what they mean in the USA
Checked against the official pages on 22 October 2026. How we check.
The six cases are in Article 5-1, added to the Law “On Citizenship of Ukraine” by Law No. 4502-IX (law text, in Ukrainian). The Embassy summarizes the change and confirms that it entered into force on 16 January 2026 (Embassy citizenship page, in Ukrainian).
The six cases
| Case | What the law says | Typical situation in the U.S. |
|---|---|---|
| 1 | A child gets Ukrainian and another citizenship at birth | A child born in the U.S. to a Ukrainian parent |
| 2 | A Ukrainian child adopted by foreigners gets their citizenship | Adoption by U.S. parents |
| 3 | A Ukrainian gets another citizenship automatically by marrying a foreigner | — |
| 4 | An adult gets another citizenship automatically under foreign law, without receiving a document of it | A citizenship that comes by descent without papers |
| 5 | A foreigner from a simplified-route country becomes Ukrainian | A U.S. citizen by territorial origin |
| 6 | A Ukrainian becomes a citizen of a simplified-route country | A Ukrainian who naturalizes in the U.S. |
The left two columns follow Article 5-1 (law text, in Ukrainian); the right column is our reading of where Americans fit.
The U.S. is one of the five simplified-route countries: the Embassy names Poland, Czechia, Germany, Canada and the U.S. as the countries whose citizens sign a declaration instead of renouncing (Embassy citizenship page, in Ukrainian).
Only Ukrainian for Ukraine
Article 2 keeps the principle of a single citizenship: a Ukrainian who acquires another citizenship is treated in legal relations with Ukraine only as a Ukrainian citizen (law text, in Ukrainian).
The Embassy spells out what that means for Americans who gain Ukrainian citizenship: Ukrainian law applies to them, military duty included (Embassy page, in Ukrainian).
Men aged 18 to 60 need the Reserv+ e-military document for most consular services; see our military registration guide.
When citizenship can be lost
Article 19 lists the grounds for losing Ukrainian citizenship. The first is the voluntary acquisition, as an adult, of the citizenship of a state Ukraine’s parliament has declared an aggressor or occupier, or of a state whose citizens cannot use the simplified route.
Cases 1 to 4 of Article 5-1 do not count as voluntary (law text, in Ukrainian). Since the U.S. is on the simplified list, our reading is that U.S. naturalization falls under case 6, not under that ground.
Other grounds in the same article cover false documents in a naturalization file and contract military service for an aggressor state. None of them is about where you live.
What it changes in practice
For a family in the U.S., the new rules mostly mean less paperwork.
A child born after 16 January 2026 to two Ukrainian parents is Ukrainian by birth and no longer needs a citizenship registration, while a child with one Ukrainian parent still does: see a child born in the U.S.
An American with Ukrainian roots can apply through territorial origin without renouncing. And anyone who wants out of Ukrainian citizenship still follows the long route in renouncing Ukrainian citizenship.
