M: Hello. I need to talk with someone about my driver’s license.
W: Yes. How may I help you? Do you have a driver’s license, or do you need to get one?
M: Well, I’m not sure. (19)You see, I have an international driver’s license.
W: Uhuh. And how king will you be staying in the United  States’?
M: Probably four years, until I finish my degree.
W: Oh. Then you will need to get in Arizona driver’s li cense.
M: Do I have to take a driver’s test to do that?
W: Yes, you do. (20)You need to come in and take a  written exam and an eye exam, and then you need to take  a mad test with a parallel parking test. Did you say that  you are a student?
M: Yes, I’m a student at the university.  (22)I don’t have  ID with me, but I can go and get it.
W: Okay. Then you (20)can apply for a limited license.  Just come back and show your student ID, and you can  make application for a five-year license.
M: Great. That’s what I want. So I don’t have to take the  driver’s test then.
W: Oh, yes you do. The limited license only costs you ten  dollars. A regular license would cost you a lot more than  that, (21)but it is valid for more than five years.
M: Why can’t I just use my international driver’s license?
W: You could if you were just visiting a lot less than a year.  But as a student, you will be temporarily residing in our  state.
M: Okay. So that’s why my friend can use his international  license, he is a tourist.
W: Right.
