Alhamdulillah, with grace of Allah, I have got US Visa. Visa or no Visa, I thank almighty for all his blessings.
Day 1: Carry most recent passport, DS-160 confirmation, Appointment letter. They check document, issue a coupon and route you to a window. They take a picture and fingerprint.
Day2: Long line outside the Consulate office. Reach 30 min before time. stand in queue with your passport. They check passport and let you inside the building. you can not carry bag, laptop, mobile. I only carries all my documents in a folder and my wallet. There is a security check inside then you need to wait for your turn in an open lawn (it has shed so dont worry about rain).
Then there is another queue to second building, they take your passport and do fingerprint again. Then you are in a queue for the interview. there are 10-15 window and by large I have found all the VO very good; all they are checking is that you have a specific purpose for the visit, you have finances to make for your trip and strong tie with your local country hence strong reason to come back. Here is how my interview go:
