Business Visa - B1

I had applied for B1 and my interview happened at Chennai.
there will be security checks at all the levels through out. please don't carry mobiles, bags etc. carry your documents in a simple and transparent file.don't carry documents in a closed envelopes. they will send people to go out of office to open it. there was a guy who has been shouted at and asked to go out to open.

Day 1 - OFC - There nothing to be tensed about this. you just arrive at the OFC for your biometrics atleast 45 minutes before your appointment. My appointment was at 8.30. I reached there at 7.45. there is a big queue on the footpath beside the OFC office. they started allowing people from 8.15. have your Passport, DS-160 confirmation page and Appointment letter handy. in the OFC they had alloted a token number. when my turn came, just went there and gave my fingerprints and photo has been taken.

Day 2 - US Consular office - My appointment was scheduled at 7.30AM. I arrived there by 6.30AM and by that time there was a huge queue outside of the consular office. there were around 70+ people already. I just joined the queue. at around 7.20 they started moving the line. there are several security checks all the way. you will be alloted with ticket number for interview. even in the main hall there insufficient seats to sit before your turn comes. there you'll be checked with your finger print scanning again before interview.
there are several tv monitors that shows the ticket/token numbers and counter. when my ticket is appreared on the screen i just joined the line at that counter.

I am sharing a couple of experiences here. One is my own and another is one of the guy's experience who was before me in the interview.

Other Guy before me, he came for Student VISA F1. the officer has played with him with some different questions.

1. Why do you want to do Masters?
2. your bachelors degree pass percentage is low, do you think, you can clear master's in US with these skills?
3. what if you can't clear your backlogs?
4. What alternatives you have, if you can't clear the Masters?

and more.

Mine
Me - Good morning
Officer - Good morning, passport please.
Officer - Why are you going to the US?
Me - Technical training.
Officer - for which company are you working for?
ME - XYZ name.
Office - Sorry, come again
Me - Repeated.
Officer - for How long is your visit?
Me - One week.
Officer - Are you going to a client's place or your internal?
Me - Internal.
Officer - (was typing something) Ok, Have a good trip.
Me - Thank you.

I silently moved out from there.

Tips:
1. please be prepared for all kinds of questions.
2. prepare that you may face the worst case scenario.
3. don't carry anything else other than your documents in a transparent file and a wallet if needed.
4.even if you are nervous, hold it. you need not to show any confidence/smile but have a normal face without any nervous.
