NOGALES, AZ - DECEMBER 10: U.S. border official Marshall Walcer inspects the identification of a Mexican citizen at the U.S.-Mexico border crossing on December 10, 2010 in Nogales, Arizona. Despite Arizona's tough immigration enforcement laws, thousands of Mexican citizens have permits to work in the U.S. and commute daily from their homes across the border in Mexico. Border crossings, known as "ports of entry," are run by the U.S. Office of Field Operations, which is part of the department of U.S. Customs and Border Protection. Port personnel are the face at the border for most visitors and cargo entering the United States and are authorized to stop, question, search and examine everyone entering the country.
