4. Germany
Germany is more or less an obvious choice when one needs to decide where to go in search for the better living conditions. It is why this country is highly ranked, with the percentage of foreign-born people around 14.9. On the other side, the number of illegal immigrants is also quite high, but Germany has certain rigid measures to prevent illegal immigration. The magazine Telegraph even brought the news that the German police arrested around 57,000 of them in 2014 and that the number increased by 75% in comparison to the year before.
