Which of the four Nordic countries can immigrate? How to apply for immigration?

Hello, the direction is very good, but the four Nordic countries are countries with high welfare and high treatment, but they are not immigrant countries. It is difficult to naturalize. Polish immigrants can be considered as EU citizens after three years of naturalization. According to the Lisbon Treaty, EU citizens can live and live in EU countries without restrictions.

Hope to adopt thank you! Our skilled immigrants in Canada are RMB 300,000, and there is no charge for failure! !
