Working for a UK company that provides services in Norway.

Hi all

I'm a newbie here.

I am living in the Uk on PR (not a citizen yet but hopefully in 6 months). I'm a Pakistani citizen.

I have been offered a job by a company that provides services in Norway. They need me to go to Norway every 3rd week and stay there for a week to provide services.

1. What sort of visa would I need in this situation.
2. Would you also be able to provide a link which explains the routes to apply, forms to fill and documents to be sent with the application. And any other info.

Many thanks
