You can, however, apply to stay abroad for more than two years without losing your permanent residence permit if you are to settle in Norway again after your stay abroad. However, this only applies if you:
are to serve your military service or other equivalent service in your home country
are to stay abroad in connection with work or education over and above upper secondary school
are to stay abroad together with a spouse, cohabitant or parents staying abroad in connection with work or education
In order to be eligible for a permit to stay abroad for more than two years, you must submit an application to the Directorate of Immigration well before you have spent two years abroad. If you have submitted your application more than six months before the two-year deadline expired, you will not lose your permanent residence permit if you return to Norway within two weeks of being informed of a rejection of the application.
You must be able to document the purpose of your stay abroad.
How long you will be permitted to stay abroad depends on the duration of your subsequent connection with Norway and the purpose of the stay abroad.
