I'm still a bit surprised these weren't available in English.

It isn't the language of the country, but children start learning it at age 6. A lot of masters and PhD courses are taught in English, and some workplaces use it quite a bit, especially if they do collaborations with other countries. This would fall in that last category. I can find a lot of information from the government in English, and all of my immigration paperwork was in English - they don't require you to further translate into Norwegian.

I can mostly get by using English, but Norwegian is needed to integrate and it makes a social life easier. norwegian is necessary for most jobs, though.

Edit: To illustrate it even more: Graffiti is in english half of the time and Norwenglish exists.
