If your partner will be accompanying you to Stavanger, her or him finding meaningful occupation can be an inportant factor for a successful stay.
Depending on personal circumstances this might involve further education, starting or continuing a professional career, getting involved in charity work and, most importantly, creating a supportive social network.
Most jobs in Norway require a good knowledge of the Norwegian language. Online Norwegian Courses, see Living in Norway.
We recommend the spouses / partner to learn Norwegian and to socialize. Be a volunteer and do both!
