H1B, H4 Visa

Attended on VO morning session.. there are many applicants(150-200) by 9:30 AM
It is going to take at-least 2 hrs to reach to VISA Office. Luckily there are many counters

VO: GM
me: GM Officer and how are you doing today?
VO: replied
VO: Which company you are working?
me: answered accordingly ... xxxx company
VO: What does you company do?
me: explained details of what my company does
VO: What is your role in it?
me: answered
VO: Where is it located
me: answered the location
VO: DO you work at company location?
me: answered accordingly
VO: Is this your 1st time attending to US?
me: answered accordingly ..

VO: thanks your VISA is approved.

I have over heard some VISA Office questions to..

For H1 B Visa who are travelling for some conference's ..If you are travelling with your team, VO asked
>details of with whom you are travelling?
>Is your co workers applied for VISA? If yes when are they planning to attend?
> Questions on Job details

For F1 students
>Make sure you read the I-20 carefully
> If VO asks for complete fee for 2 years you answer it correctly (I think I-20 has only 1yr of fee)
If you are having siblings in USA and you have mentioned it.. make sure you can answer their status according to their VISA status(If on F1 and you sibling is working now.. you should be mention he is working on OPT and don't just go blank when VO asks questions)
>Questions on subjects you are taking.. why you choose them?

I hope this helps someone or give some confidence..
Good luck guys.. ALL THE VERY BEST
Thanks
