grounds for the decision
as a general rule a residence permit must be granted prior to the foreign national's entry to Norway, cf.section 10-1 first paragraph of the immigration regulations. consequently, an application for family immigration must be submitted from a foreign service mission in the applicant's home country, or the country where the applicant has had a residence permit the last six months.
pursuant to circular 2013-001 from the Norwegian Directorate of Immigration, Foreign Service missions are given the authority in certain exceptional cases to grant foreign nationals a limited entry visa for the purpose of applying for family immigration in Norway. Like also applies when the foreign national already has submitted such an application, and would like to stay in Norway while the application is being processed.
