Dear Venkayya,
congrats!!!
Could you please confirm that your case is an employment based one. My concern is that INS has never (per my limited knowledge) requested marriage certificates for I-485 processing. I am, for no reason, questioning your competency on your own immigration case. Just to make sure, since I am a derivative applicant on the verge of divorce. Therefore, a-proof-of -marriage situation is a hot topic for me.
Thank you.
