If you are getting married to a person who lives in Norway, and you wish to marry in Norway, you can apply for a residence permit in order to do so. It is however not a requirement that you have exactly this type of residence permit when you get married in Norway. You can also get married in Norway if you have a different type of legal stay.
It is possible to get this type of residence permit if you are coming to Norway to get married, and it is therefore often called a “fiancé permit”. You cannot get this type of residence permit if you wish to come to Norway to find out whether you wish to get married, or in order for you to get to know your boyfriend/girlfriend better.
There are some requirements you and your fiancé must fulfil, and there are many documents you must hand in with the application. Before you hand in the in the application you must check that you fulfil these requirements.
This residence permit is valid for a maximum of six months. You must hand in the application for a residence permit with your spouse at least one month before the residence permit for getting married expires.
This means that you have less than five months to get married. On the Tax Administration's website you get an overview of what you have to do to get married (external website). There is a lot you need to do during these five months, therefore it is important that you start the formal processes surrounding the marriage as early as possible.
