H1B, H4 Visa

OFC on 14-Nov-2016: Was pretty simple. They just take your photo and fingerprints. My appointment was @1pm, I went thr by 12.45 and came out by 1.15. Just go 15 min early to your appointment time. Keep ds160 confirmation, passports and Appointment letter handy. No other document is needed here. You can carry your mobile.

PAI on 15-Nov-2016: My appointment was scheduled at 9.30am, I reached the venue by 9. I skipped the queue multiple times. Thanks to my 4yr old Son. I entered the queue at 9.05am and you will be allowed inside the building after security check. There was another small queue inside the main Consulate builing where they verify the passports. After that they verify your fingerprints. At 9.20, I was sitting and waiting for my interview with VO(you will stand in queue if you don't have a kid along with you) . Since the appointment was at 9.30, they asked me wait for sometime. Around 9.25 I was guided to a counter . gave all passports to VO and he asked only 4 questions,
VO: Who is your employer?
VO: Who is your Client?
VO: What do you do for your client?

VO to my wife: What is your highest qualification?

He then type something in his computer and said the golden words and that I can collect my passport in 4 days. He gave a white pamplet. At 9.35, I was outside the Consulate.

Key points:
You may not understand what Vo is asking if you don't pay attention.
