There are now 40.7 million foreign-born residents living in the USA. This makes foreigners the most populous "state" in the country; the total population of California is only 38.3 million. The top ten source countries:
1.Mexico: 11,489,387
2.India: 1,974,305
3.Philippines: 1,861,996
4.China: 1,719,819
5.Vietnam: 1,264,188
6.El Salvador: 1,254,501

8.Korea: 1,105,653
9.Dominican Republic: 960,211
10.Guatamala: 880,869
Of course, this doesn't even begin to account for the "American" citizens who are foreigners born in the United States.
