I got it!!!
had my AOS interview today with Officer A. He was OK. very fast.
He asked my spouse some questions like "my DOB", parents name, marriage
date etc. He asked for Birth Certificate of my children, my Birth certificate, passport, all I-94s, all EADs, Bank statements, last three year tax returns, Affidavit of support, I-693, my spouse passport, certificate of citizenship etc.
He asked for two passport size photos. He put all copies in his file and gave
originals back. Then stamped on my passport and told me "Congratulations".
It took only 20 minutes. For those who are going for the interview, please make sure you have two passport size photographs. It is not in the checklist sent by INS.
