Immigration and Emigration

The number of illegal immigrants peaked at an estimated 11.9 million in 2008. About 11.2 million illegal immigrants were living in the United States in 2010, a number essentially unchanged from the previous year, a 2011 study showed. Arizona passed a law that would allow officers to check a person's immigration status while enforcing other laws and that required immigrants to carry their papers at all times. Legislative leaders in at least half a dozen states have said they will propose bills similar to Arizona's law.
