The undocumented parents of a 10-year-old US citizen whose family was removed to Mexico say they are desperately seeking a way for either of them to return to the US with the girl so she can continue brain cancer treatment. The girl's care was interrupted last month, when she, her parents and four of her siblings were detained at a Border Patrol checkpoint in Texas and were subsequently removed from the US to Mexico following the parents' decision to take their children with them rather than separate, according to Texas Civil Rights Project (TCRP), an immigration nonprofit representing the family. The parents have "no criminal records," according to Danny Woodward, an attorney with TCRP. All but one of the couple's children are US citizens, TCRP said.
