4. Norway
This country is not a member of the EU, but it is a member of European Economic Area (EEA), in the context of being a European Free Trade Association (EFTA) member, making it one of the most convenient countries to live in Europe. There are, like in most cases, two types of residence permit in Norway, and people who want to immigrate to this country should be aware of it. In all cases, in first several years, you obtain a temporary residence permit, based on your education, job, marriage to a Norwegian citizen, or based on Norwegian roots in your family. This country is amazing, so it should be definitely taken into consideration if you want to immigrate somewhere in Europe.
