H1B, H4 Visa

Hi All,
I have found this site really helpful while preparing for my H1B interview. So I thought I would share my experience with all, so that others might find it helpful.
I had my interview on 27th February in Mumbai.I reached there 1 hour before my interview time and since there is a long queue , I think its useful to reach early.
Once I was inside, my interview confirmation letter was checked and I was given a token number. Following that I went through the security check and then moved on to the waiting area. After sitting in the waiting area for about 15 minutes, I went inside the main interview zone. There I was finger printed and then I waited for the monitor to show up which counter would I have to go to. After waiting for approx 20-30 mins my token number came up on the monitor along with the counter number. I proceeded to the counter and greeted the VO and gave my passport and I-797 petition.

The following questions were asked to me

1) Which company you work for?
Ans: XYZ
2) How long have you been working with the company
Ans: X years
3) What do you do there
Ans: Explained about my role and responsibility in detail
4) What will be your Salary in US
Ans: X per annum

After the VO checked something on the screen
5) Will you be working at Client side in US?
Ans: Yes (my petition had the client address as my work location)
6) Who is your client?
Ans: XYZ
7) Is there a manager from your company who is working at Client Location?
Ans : Yes
8) Whats your highest qualification
Ans: BE with my speciallization
9) Have you travelled to US before on Business?
Ans: Yes (I had travelled on B1)
10) For how many days were u there?
Ans: X days
11) What were you doing there for X days?
Ans: I explained my purpose for travelling on B1.
12) Are you married ?
Ans: yes
13) Is your wife travelling with you?
Ans: No

The VO looked at the screen for some time and then said that my visa is approved and I will get it in two days.

I got my Passport stamped with H1B visa today. However they have cancelled my B1 Visa . I think the reason for this is I cannot have two valid US visas while travelling to US.

I wish good luck to everyone who is going for their stamping.
Before you go ensure that you have all the required documentation and prepare urself for the interview. During the interview have faith on urself and be confident of what you say, answer all questions truthfully and with some luck you will surely get the visa.
