想聊就聊-4.01.1关于护照（在线收听）

Hi,Dollers,I hear you are going to United States next week?

So I am.

When did you get the passport?

I got it last week.

How long is it valid?

It follows for five years.

I'm applying to do a doctor's degree joining my stay there.

Good,good luck to you.

Thank you very much.
