Your citizenship was granted on false pretences
If you have provided incorrect or incomplete information in your application, or if you have intentionally withheld key details, and this was very important to the decision to grant your application, you may lose your Norwegian citizenship.
Children’s citizenships are normally not revoked
Children’s citizenships will normally not be revoked on the grounds of mistakes committed by their parents or grandparents. This also applies to children who have reached the age of majority, but who were under the age of 18 when they applied for, or were granted, Norwegian citizenship. A child’s citizenship can be revoked in some cases if the child does not have a strong connection to Norway.
If the child’s citizenship is not revoked and the child is registered with an incorrect identity, UDI can correct the information.
