First of all thanks to all users to share their experience in Immihelp because this help me a lot to prepare for interview.

I had visa interview for H1B on Mar 06 @ Dubai consulate.
I went with my wife and daughter.

The VO is a very nice lady. She asked me the following documents and questions:

Documents asked:
1) Passports
2) I-797

Questions asked:
1) Who is your Petitioner?
2) What are they (Employer) doing?
3) You have a client?
4) Where is the client location?
5) How many years are you in Dubai?

After that she told your visa is approved.

Be confident.
