在以下对话中，一家人谈申请美国旅游签证所需手续。
Sam: Did we book our flights yet for our trip to the U.S.?
Claudine: Sam, first we need to get our visas. When do we go to the U.S. Embassy for our tourist visa interviews?
Gina: We have a lot to do before going to the interviews. First, we need individual pictures of each of us. There are photo requirements, so we probably should go to a photography studio that takes passport photos.
Sam: What else do we need to do?
Paul: There’s a form to fill out. After we complete the form, we must print the confirmation page. We need to bring that page to our interviews.
Gina: And we have to schedule our interviews at the U.S. Embassy.
Paul: And I’ve checked our passports. All of our passports are valid for at least six months after our trip.
