出國通關(guān)

    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？

    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.
