We are a couple of Italian parents. Our daughter, 16, is going to move to Dale City, in the Birchdale neighborhood, for few months, within a school exchange program. She will go to Gar Field High School. The family and the school were selected by the exchange organization and just communicated to us, we didn't have a chance to do any advance research on it. Can anyone provide comments about the neighborhood/the school and offer any tips? thanks
