clearwater,
Thanks for the encouraging words....
At the time of filing I-485, I submitted a copy of my birth cert along with (2) affidavits from parents and relative. But since my birth cert. was issued only a couple of months prior to my I-485 filing date, the RFE asked me to furnish an earlier record of birth and parentage. As per my attorney's advice, I submitted copies of my school leaving cert. and marks sheet of my 10th std. cert. both of which contain the reqd info.
