How many years of financial status should the man offer?

W: Good morning!
M: Good morning!
W: I’d just like to ask you a few questions about your visa application.
M: Sure.
W: For you student visa, we need evidence of your last year’s financial status.
M: I think I offered the evidence that you need.
W: (1) But in your application, you only included it for four years.
M: Really? Let me check if I have the document here... yes, here is the document you need. I’m sorry. I must have forgotten to make a copy of it for you.
W: Thank you. (2)The document relating to your education is fine. The offer from the university is conditional on your English language proficiency test result. Do you have that yet?
M: Not yet. I took the test last weekend. (3) The results will be available in another two or three weeks.
W: Ok. Everything else is in order. (3) I’ll be happy to give you a student visa, valid for the duration of your course, when you bring me a certificate showing the result of your language test.
M: Thank you very much. You don’t need any other document from me to process my application?
W: None. Make an application to see me when you receive your results.
M: Ok. That’s very kind of you.
W: When you bring the certificate to me, bring your passport, too. Then I can give you the visa.
M: Thank you very much.
W: Glad to help.
