Eufronia Alba walks her daughter, Danna, 7, and son Nathan, 4, to the bus stop near her apartment in Arlington, Va. on Dec. 15, 2016. Alba and her husband, undocumented Bolivians, were in deportation proceedings but have requested cancellation of removal because Joshua, who is American-born, has cerebal palsy and depends on his parents for everything including bathing and feeding.
