5. United States
Honestly, I would expect this country to be the first on the list, but all in all, it is still highly ranked. The percentage of foreign-born people in the United States is 14.9, and the situation is also quite similar when it comes to illegal immigrants. According to the Pew Research Center, the number of illegal immigrants in this country was around 11.3 million in 2016, and that number is quite similar to the statistics provided in 2015 and 2009. The biggest number of those immigrants comes from Asia and Central America.
