Well, I mean, if I wanna practice law, that is. All countries have their own legal systems. Many of them are very much alike eachother, but to practice law in a country you have to meet that particular country's requirements to practice law there. My education only qualifies me to practice law over here.
There are some big norwegian law firms who have offices in places like London, Shanghai, elsewhere in Scandinavia etc., though, but that's pretty much it.
Oh, and there's of course EU/EØS law, that allows us to work elsewhere in Europe, but I didn't go that route.
