I wore polo shirt slacks on my interview.

I could say that I am the luckiest among the applicants scheduled for interview on that day at the US Embassy. I was scheduled for interview on a Friday, The consul asked my name, and my company name he just murmured" I know this already". The consul asked when is my flight schedule and I told him that my flight will be on Sunday. He asked me to wait and he left. When he came back he gave me my passport with US visa in it.
