HOUSTON (AP) - A flight attendant who traveled to Mexico for work through a program for immigrants brought to the U.S. as children has been detained.

Attorney Belinda Arroyo said Friday that 28-year-old Selene Saavedra Roman raised concerns about whether she could work an international flight due to her immigration status.

Arroyo says Mesa Airlines mistakenly reassured the enrollee in the Deferred Action for Childhood Arrivals program.

U.S. authorities stopped Saavedra Roman on her return to Houston.

Mesa Airlines apologized and joined the Association of Flight Attendants in asking for her release.

Immigration and Customs Enforcement says Saavedra Roman didn't have a valid document to enter the country.

U.S. Citizenship and Immigration Services says on its website that those who travel outside the country without permission are no longer covered by the program.
