You do not need a schengen visa, however you would have to apply for a Norway Transit visa. The documents for that are quite shortlisted and can be provided easily. They only include the following:

1. Ticket to the destination country and visa (if applicable, which in this case is not required).
2. Accommodation papers for at least the starting days.
3. Proof of funds via bank statement of the last 3 months.
4. 2x passport size photographs (recently taken with in the last 3 months).
5. Fee of ~80 EUR depending on your country and age.
6. Transit visa application, that can be found on the Schengen EU website.

That pretty much sums it and then there is only wait of up to 2-3 weeks to get a response and you are all set.

I am from Pakistan and I am applying and am in process and want to settle down there for good.
