Does Montenegro allow dual citizenship? (2026)

Does Montenegro allow dual citizenship?

As a general rule, no. Montenegro's Citizenship Act treats nationality as exclusive: someone naturalising is required to renounce their previous citizenship (or show they will lose it), and a Montenegrin citizen who voluntarily acquires another country's citizenship loses the Montenegrin one. This is the opposite of the recent liberal reforms seen in countries like Germany.

The catch to watch

The automatic-loss rule cuts both ways. If you are already Montenegrin and later take, say, an EU passport by naturalisation, you can forfeit your Montenegrin citizenship — not just be barred from adding a second one. There are exceptions, but they are narrow and specific, so this is not a country where you can casually stack passports.

The narrow exceptions

Dual citizenship is tolerated where it was already held before Montenegro's independence on 3 June 2006; where a bilateral treaty with another state provides for it (Montenegro has long discussed such a treaty with Serbia, but none is in force); and for people naturalised under the special investment programme that ran until the end of 2022. Outside these boxes, the single-nationality rule applies.

No open investment-citizenship route

Montenegro's citizenship-by-investment programme closed to new applicants on 31 December 2022, under pressure from the EU during accession talks. Grantees from that scheme were allowed to keep dual status, but the door is shut — do not treat a Montenegrin passport as something currently buyable. Naturalisation today runs through residence, and it is a long road.

How Montenegrin citizenship is acquired

By descent from a Montenegrin parent, by birth in specific circumstances, by marriage to a Montenegrin (with residence), or by ordinary naturalisation — which generally requires around ten years of legal residence on a permanent-residence basis, language and other conditions, and renunciation of your prior nationality. Emigrants and their close relatives can qualify on shorter residence.

Where it fits in a borderless plan

Montenegro can work as a base rather than a passport play. Many people use its tax residency and residence routes without ever chasing the passport. Pair a base here with a low-tax residency and a self-custody plan for your Bitcoin. New to nationality planning? See which countries allow dual citizenship, or claim one through ancestry.
