Which of the following is NOT true according to the conversation?

M: Hello ,Miss Smith! So glad to see you!
W: You must be kidding! I’ve been here hundreds of times for the visa, so you couldn’t say that.
M: But today is different. I was just going to let you know the visa has been granted.
W: Oh, dear! I’ve been waiting for nearly six months by now.
M: That’s not very long, compared with the time it took many other visa appliers.
W: This, I suppose, is British efficiency.
M: Let’s not put it that way, please! You should know, Miss Smith, with so many immigrants in Britain already, the Immigration Office has to take precautions.
W: To tell you the truth, if I want to stay in another country for good, I certainly wouldn’t choose Britain.
M: Why?
W: As I know, the cost there is very high compared with that in America, Switzerland, Sweden and other western countries. Besides, England is well known for its bad weather.
M: Yes, we have maritime climate. But what puzzles me now is why you have applied for a British visa after all?
W:  The answer is quite simple: I happen to be a student of English and I want to get an M. A. degree. I’ve decided to go to London University, even if it rains everyday in England.
M: I see! No wonder you speak such fluent English.  Here’s your passport and the visa is on this page. Now you can go and get your health certificate.
