Help required on 221g for H1 in Chennai

[rajandgr8]

Hi,

I attended my H1 Interview along with my dependent(H4) on 11th Dec 2012.
VO gave 221g and told they need additional administrative process required.
Yesterday I got a call from Chennai Consulate, they asked me to appear again for general discussion
and got an appointment time from me(for next friday).

Had any one gone through this process?
I did not get any appointment/confirmation mail from them till now, what should i do?
what are the documents should that I carry again?

Help me.
