Hi, I'm an international applicant and I've received an unconditional offer about three weeks ago. I was wondering if I am going to receive an offer letter by post or would I receive one after I reply to the offer? because a friend of mine who was given an unconditional offer three days before I got mine had already received her letter a week ago. So this got me confused as to whether I'm going to receive one/have received on but it has gotten lost in the mail or I'm only going to get one once I reply to the offer.
Or does it play no part?
