Hello. Is everything OK, there?
I'm having a little trouble with this form.
What seems to be the problem?
There are two types of L / C here and I'm not sure which one I want.
That's right, there's'revocable'and'irrevocable'. We usually go for the irrevocable one, it's the most popular.
So, I should choose that one?
I would recommend it, yes. Then you just need to complete that form.
I see. It's very nice of you to help me. Is this form alright?
