A relevant question. The answer is zero. It is much more convenient to pay extra taxes and get an organized integration. That can also be read as not wanting to make a serious effort on my behalf, of course.
About 75% of refugees and those seeking asylum are granted a stay in Norway. Considering that there will always be a minority in search of a better life without an actual need for protection, that figure is probably decent.
However, our most right-wing party - which probably is almost as right wing as the Democrats in USA overall (not kidding) - is part of the government and they want the number of people coming to Norway for protection to be zero. Zilch. Instead, they want to help people in need where they are, because for the same amount of money you can then help 30 times more people.
That is an argument I can understand and agree with, but there are always those who simply cannot be helped where they are. Or who have escaped and cannot be returned safely. Hundreds of thousands of refugees are flooding Italy and Greece and Turkey in particular, and we cannot expect them to take the burden alone. Especially since their economy is much worse than our.
So back to the original question, I could add; do I want to? No. Nor do I want to house anybody else outside my immediate family, whether they are Norwegians or foreigners, no matter how much in need they are. I am willing to pay my share for them to get help, but I am not eager do actually do much. Not very noble
