Au pair programs and visa information in Norway:
In order to become an au pair in Norway it is necessary for an individual to apply for a work permit at the Norwegian embassy of their home country before going to Norway. The au pair is only allowed to enter Norway if he or she holds a valid work permit. The au pair must have a job offer in Norway before he or she applies and the permit must be applied for and granted prior to entry into Norway.
Thus, in order to be issued a work permit, the au pair needs an "Offer of Employment" contract signed by the host family as a proof of the job offer, which is required to accompany their application to the Norwegian embassy of his/her home country. The au pair can obtain application forms from the Norwegian embassy or consulate in his or her home country.
Once the application has been made the embassy will forward the application to the Norwegian Immigration Directorate (UDI) and when it has been approved the work permit will be granted and the au pair can make travel arrangements to go to the future host family in Norway. On average, the application takes 3-6 months.
