Why don't you sit down? Now there are several questions I must ask you if you don't mind.
Not at all, go ahead.
What is the purpose of your visit to the state?
I'm going to attend a conference on air pollution.
When and where is this conference being held?
It's being held in the first two weeks of February at Stanford University in California.
Who will pay your expenses?
Stanford University. Here is the official letter of invitation.
I see, fine. When do you want to go?
I'd like to leave in mid January of my passport is ready by then.
That shouldn't be difficult. Why don't you found me about January tenth? I should be able to give you an answer then.
Thank you.
