Dual Citizenship Recovery for Norway citizens in the United States — 2026

Nationality rules differ enormously between countries, and this is not a page that can tell you whether you qualify. Some countries pass citizenship down indefinitely; others stop at one generation born abroad, require registration before a deadline, or do not permit dual nationality at all. What follows is how to find out for Norway, and what to settle before you spend anything.

Quick facts

Norway maintains a comparatively large consular network in the United States: fourteen consular offices, in Anchorage, Boston, Chicago, Coral Gables, Denver, Fountahills, Houston, Los Angeles and six more. That is a help and a trap at once, and the trap catches more people than the distance does.

Norwegian consular offices in the United States

Applications and enquiries go through the career post whose district covers your state, though the decision itself is taken in Norway:

The questions that decide your case

• How far down does descent run? Through a parent is common; through a grandparent is much rarer; through a great-grandparent is unusual anywhere.
• Is there a deadline? Several countries require a child born abroad to be registered within a set period, after which the claim is lost.
• Does Norway permit dual nationality? Yes, since 1 January 2020. Before that date acquiring another citizenship caused loss, and the change was not made retroactive: if you naturalised earlier, you have to apply to get Norwegian citizenship back.
• Does the line pass through either parent? Some nationality laws were paternal for decades and were reformed later, sometimes with retroactive effect.
• What obligations come with it? Military service and tax residence attach to nationality in some countries regardless of where you live.

Documents a claim by descent normally rests on

• Birth certificates establishing the unbroken line, each certified for use abroad.
• Marriage certificates covering every change of surname in that line.
• The ancestor’s Norwegian passport, identity card or other proof of nationality.
• Evidence of whether and when an ancestor naturalised elsewhere, which in some countries breaks the line.
• Translations into Norwegian where required.

Before spending money on this

Ask the consular office what Norwegian law actually allows in your circumstances before engaging anyone to help with it. Genealogists and specialist firms exist and can be useful where records are old or scattered, but they are not a substitute for knowing whether the claim exists at all — and that answer is free.

If your own immigration position in the United States is unresolved, take advice from an immigration lawyer before approaching any foreign authority.

Norwegian citizenship and the U.S. oath

Norway abolished the single-citizenship principle with effect from 1 January 2020. The foreign ministry states that from that date Norwegians can become citizens of another country without losing their Norwegian citizenship, and that one or more citizenships alongside the Norwegian one are permitted.

It was not made retroactive. Someone who became a U.S. citizen before 1 January 2020 lost Norwegian citizenship then and does not get it back by itself: they must apply to regain it. People who had previously been required to renounce a foreign nationality to become Norwegian are released from that requirement by letter from the UDI.

The age-22 rule. A person who became Norwegian at birth and has not lived in Norway for at least two years, or in the Nordic countries for at least seven, must apply to keep the citizenship before turning 22.
