Answer:From 2006 to 2009, the two regions that have provided the largest number of United States immigrants were Latin America and Asia.
Step-by-step explanation:
In this period, 27% of US residents born abroad were from Mexico. 17% came from other Latin American countries, including El Salvador and Cuba.

The Permanent Resident Card, popularly known as the Green Card, is an identity document for permanent residents in the United States who do not have American citizenship. The holders of this card have the right to reside and work in the country. However, they must maintain the status of resident in the United States although it can be withdrawn if it is proven that they have committed certain crimes.
