resend

I don't know why they didn't return the docs to your parents.maybe they will double check..but since they already got the visa,it will be fine. I think you could resent the copy docs to them in case they need it in the Customs.Also let your parents have your cell phone number in hand.so officer can talk to you directly by phone if your parents get any trouble. as I talked before, my friend's parents bought the one-way ticket, so the officer called my friend's cell phone and asked bunch of questions, then let them through. at that moments, we all worried about them since our parents could not speak any English.
