TIJUANA, Mexico (AP) — Henry Monterroso is a foreigner in his own country. Raised in California from the age of 5, he was deported to Mexico in 2011 and found himself in a land he barely knew.

But the 34-year-old Tijuana native feels right at home as soon as gets to work at Call Center Services International, where workers are greeted in English. Monterroso supervises five employees amid rows of small cubicles who spend eight hours a day dialing numbers across the United States to collect on credit card bills and other debts.
