H1B, H4 Visa

Thanks to all comments and experience shared in immihelp which helped us a lot.
My Interview is on 16 April 2012 @ 9.30.A.M in Chennai Consulate. I went with my spouse and 2 1/2 year old daughter.
I reached Consulate at 9.A.M and was allowed to step inside the consulate and got a token number which will be used till we speak with the visa officer. All formalities are over and we reached the other building and waited for my token to appear on the screen.
