The Norwegian Directorate of Immigration (UDI) is responsible for the implementation of the new rules.
For Norwegians living in the US, this may affect you if:
1. You are a Norwegian citizen and want to apply for US citizenship. Starting January 2020, you will no longer automatically lose your Norwegian citizenship by becoming a citizen of another country.
2. You previously lost your Norwegian citizenship by gaining citizenship in the US or another country. From February 2020, you will be able to apply to regain your Norwegian citizenship if you lost it under the previous rules.
UDI is responsible for the implementation of the new rules. See UDI's website for details about procedures and more information.
Note: Regulations regarding Retention of Citizenship for persons born outside of Norway to a Norwegian parent remain unchanged.
