thanks all for such a prompt reply.
i havent yet sent my frst document itself( the date to be sent is by 22 oct.) so i guess its too early to inform the VO. and according to my immg consultant(yes i have one, and tell you its no use having one

, i should inform the VO only after the delivery. so may be i should wait. if there is any interview, i guess i ll have to request them to postpone the date.
i ll keep my fingers crossed and hope things turn out well, as a lot of time effort and money is gone in the process.
the gud thing is that my consultant will charge the fee only after we get our visa stamped

thanks again everyone.
