To understand why so few descendants of Norwegian emigrants can claim citizenship, you have to understand one decisive fact of Norwegian law: for most of its modern history, Norway did not allow dual citizenship—and this changed only on 1 January 2020. That long prohibition broke the citizenship chain for the emigrant generation, and the recent reform, though historic, does not undo the past. This guide explains the ban, the reform, and—honestly—what the 2020 change does and does not mean for you.

The long ban on dual citizenship
For most of the twentieth century and beyond, Norway operated on a policy of single citizenship: a person was meant to hold Norwegian citizenship or another, but not both. The practical consequence for emigrants was severe. Under this rule, a Norwegian who voluntarily acquired another citizenship—as emigrants did when they naturalised as citizens of the United States, Canada or elsewhere—automatically lost their Norwegian citizenship in the act. There was no keeping both; taking the new citizenship meant surrendering the old, by operation of law and often without the emigrant giving it much thought.
How it broke the chain
This is the heart of why the diaspora has no descent claim. The roughly 800,000 Norwegians who emigrated, overwhelmingly to America, and who then naturalised as citizens of their new country—as the great majority eventually did—lost their Norwegian citizenship at that moment. Once they were no longer Norwegian citizens, they had no Norwegian citizenship to pass to their children. So the chain broke at the emigrant generation itself: their children, born abroad to parents who were no longer Norwegian citizens, were not Norwegian, and neither were the generations after. This single rule, more than any other, is why Norwegian ancestry so rarely yields a citizenship claim today.
The 2020 reform
After long debate, Norway changed course. The Storting (parliament) passed the reform in 2018, and from 1 January 2020, Norway permits dual (and multiple) citizenship. Norwegians may now acquire another citizenship without losing their Norwegian one, and those becoming Norwegian need not renounce their existing nationality. It was a genuinely historic change, ending decades of the single-citizenship rule and bringing Norway into line with many other countries. For Norwegians today—and for some who lost their citizenship under the old rule—it is a significant and welcome liberalisation.
What the reform genuinely changed
The 2020 reform matters in real ways. Living Norwegians can now naturalise elsewhere while keeping their Norwegian citizenship. People becoming Norwegian by naturalisation no longer have to give up their prior citizenship. And—importantly for some diaspora families—certain people who lost their Norwegian citizenship under the old prohibition can now reacquire it, since the objection to their holding two citizenships has gone. For anyone in these situations, the reform opens genuine possibilities that did not exist before 2020.
What it did not change
But honesty requires being equally clear about the reform’s limits. The 2020 change is not retroactive in a way that helps distant descendants. It does not restore citizenship to the long-dead emigrants of the nineteenth and early twentieth centuries, nor does it make their descendants—who never held Norwegian citizenship—into citizens. It creates no new ancestry route: there is still no grandparent pathway and no descent claim beyond the child of a citizen. The reform allows dual citizenship going forward; it does not reach back and rebuild the chains that the old prohibition broke generations ago.
The false hope to avoid
This distinction matters because the 2020 reform has generated a good deal of misleading online content, some of it suggesting that Norway now “welcomes back” the descendants of emigrants or has opened a path for the diaspora to reclaim citizenship. That framing is wrong. Allowing dual citizenship is not the same as granting citizenship by ancestry, and no amount of Norwegian heritage creates a claim the law does not provide. Be wary of any service that implies the 2020 reform makes distant descendants eligible; the honest reality is that it changed the rules for the future, not the eligibility of those whose ancestors left long ago.
Who the reform actually helps
So who does the 2020 reform help? Living Norwegians who wish to add another citizenship; immigrants to Norway who wish to naturalise without renouncing their original citizenship; and, among those with Norwegian roots, the relatively few who are themselves former Norwegian citizens—people who once held Norwegian citizenship and lost it, most relevantly by naturalising abroad before 2020. For them, reacquisition is now possible. For the far larger number whose Norwegian connection is an ancestor who left generations ago, the reform, welcome as it is, does not open a door—and it is kinder to know that than to chase a hope the law will not honour.
