I came to Norway recently, but do not have residence card yet. Can I start working?
As long as you meet the requirements for the right to reside, you are allowed to work even if you have not received your residence card yet.
If it is not possible to book an appointment with the police, you must contact UDI by phone or email in order to report that you have arrived in Norway and that you are starting studies or work. You must still meet up with the police to order a residence card whenever it becomes possible.
