For more info on getting a visa, work permits and information on residence permit in Norway the website that you can get information from is UDI.no. This site has a really good information on immigration to Norway. If you go to the site, there is a choice on the right hand side of languages so you can read it in English.

I found that it was more helpful for me to actually go to the UDI office in Oslo, Norway. So if you are in Norway you can just go to the office and the people are really helpful.

I know that some of you have asked for more information on things like this and as I learn more I will continue to share it with you.
