As in most of the United States, the percentage of naturalized citizens to noncitizens in each state is divided roughly in half, though those who are naturalized generally make up the majority by a few percentage points. The percentage of foreign-born citizens in this part of the country varies from just four percent in Maine to nearly a quarter of the population in New York.

Naturalized citizens account for more than half of immigrants only in Florida and Virginia. In much of the southern United States, less than 40 percent of immigrants are naturalized citizens. However, the percentage of foreign-born residents is much smaller for most of this region as well.

The Midwest presents a varied picture of immigration, from Illinois where naturalized citizens and noncitizens are split nearly 50/50 to South Dakota, Nebraska, and Iowa where less than 40 percent of the population is naturalized. Foreign-born residents account for anywhere from 3 to 14 percent of the population in these states.

In the western United States, the state of immigration varies dramatically from the southern part of the country to the north. In California, over a quarter of all residents are foreign-born, yet this is true of just 2.1 percent of the population in Montana. This part of the United States is wildly diverse, having conditions on both ends of the spectrum.
