The Norwegian Directorate of Immigration (UDI) is responsible for visas and residence permits and has information on applications of this kind on its website.
If you had one or two Norwegian parents, you may have or qualify for Norwegian citizenship. Fill in this questionnaire to see.
The documents you are required to provide are listed on the online checklist/documentlist.
When you apply for a visa or residence permit with Travisa/VFS, be aware that it is a requirement that you register your application in the Directorate of Immigration’s online application portal. Here, you must also pay the application fee. Log onto VFS website www.vfsglobal.com/norway/usa to book an appointment for submitting additional documentation at Travisa/VFS offices. Travisa will charge a service fee, for the time being $33.00.
You must arrive at the Travisa/VFS office with all your documents at the agreed time. If you don’t have everything with you, you might have to book a new appointment for submitting your application and the documents. Incomplete applications could be rejected. Travisa/VFS will notify you once your application has been processed, and return your passport.
All foreign nationals who are required to have a visa when visiting the Schengen countries (and Norway) are obliged to have valid travel medical insurance. See the online checklist/documentlist for an overview of approved insurance companies. Without valid insurance, a visa will not be granted, unless the person concerned has been granted an exemption from the insurance requirement. All other foreign nationals visiting Norway are also recommended to have valid travel and health insurance.
Be aware that even though you have been granted a visa, the border control officer will be able to refuse you entry into Norway if you at the time of travelling no longer fulfil the conditions for having a visa. This may, for example, be the case if you cannot show the border control officer documentation that you have sufficient funds for the whole of your stay in Norway.
