Yes, if you have a permanent residence permit but do not have Norwegian citizenship, the visa rules for applicants from the country in which you have citizenship will apply to you. This may mean that the application process may take a little longer.
If you travel on an exchange, it will also take a little longer before the application for Norwegian citizenship is granted. You can apply to speed up the case on the UDI's website.
Our partner institutions will help Norwegian students who do not have Norwegian citizenship to apply for a visa. We will nevertheless note that there is always a cost in applying for a visa! The prices of this vary from country to country.
