A mariachi musician walks past a mural in the Boyle Heights area of Los Angeles, home to many Mexican migrants, in California August 5, 2014. Los Angeles is a culturally thriving city and one of the most ethnically diverse in the United States, with a population that is 48.5 percent Latino and 11.3 percent Asian, according to a 2010 census. Immigration has become a hot button issue ahead of U.S. midterm elections on November 4, and despite arguments from the White House that legal migration benefits businesses, a recent opinion poll found most Americans believe migrants place a burden on the economy.
