出国通关

I'll apply for a passport.

How long is it valid?

I lost my Visa.

I'd like to extend my Visa.

Can you tell me how to go through the customs?

I have nothing to declare.

What articles are duty free?

Can I bring this into this country?

关于护照

Hi, Dora. So, I hear you are going to United States next week.

So I am.

When did you get your passport?

I got it last week.

How long is it valid?

It's valid for five years. I'm planing to do a doctor's degree during my stay there.

Good. Good luck to you!

Thank you very much.
