Nordic citizens (Swedish, Danish, Icelandic or Finnish) staying in Norway for more than six months must report a move to Norway and visit the Tax Office for an ID check no later than eight days after arrival in Norway (external link). However, this deadline is flexible if there are no available appointments at the Tax Office within these eight days.
In addition, students must deliver a copy of the confirmation of immigration from Skatteetaten to the International Office at one's Campus of study. Drop by the Office or forward a copy by e-mail.
