Evelyn Torres cries while thinking about her son, Kevin, in her home in Tijuana, Mexico on September 15, 2017. Evelyn was arrested and deported from the U.S. four years ago. She brought three of her four children with her to the U.S. but her eldest son, Kevin, stayed in the U.S., hoping he could help his mother financially from abroad. Kevin remains undocumented in the U.S. and was in foster care until he recently reached the age 18. Evelyn hasn't seen her son in 4 years and they're only able to communicate sporadically over the phone.
