So fare in Norway the immigration has issued, not particularly unexpected but if you look at the oldest immigration groups from Pakistan it seems to work well, the younger generation seems to adapt and a lot of them takes higher education, lawyer, doctors and engineering is very popular and as always a few falls in to antisocial behaviour. Norway are not much of a melting pot except you have to melt down an become quite close to the native population. One problem we have is very few jobs for unskilled labor, that hurt integration of new immigrants and refugees as work is the best way to learn.
And there are friction around religion, here religion is a very private thing if you belive it's not expected that it shows in cloths and behaviour, that is very strange for a lot of foreigners.
And the welfare state is very tough, unless you are disabled or have bad healt its not much you get.
