Am I allowed to work while waiting for my residence card?
This depends on whether you meet the application requirements.
Information about residence cards for family members of EU/EEA nationals - UDI.
If you meet all the requirements described on the webpage, you are allowed to work while you wait for the police/UDI to process your application. You must check for yourself that you meet the requirements to obtain a residence card in Norway. You can be expelled from Norway if you work when you do not meet the requirements.
