Immigration to the U.S. from Mexico has dropped to new lows due to increased border security and the sluggish U.S. economy. Moreover, many undocumented Mexicans living in the U.S. have decided to return home.
Those who remain say living north of the border is difficult and stressful because they can't find jobs and worry constantly about being deported. Many struggle to find enough to eat and to pay their rent. In Arizona, most work odd jobs for cash because a state law requires employers to verify the social security number or work papers for all potential employees.
