Birth certificate notary used for i-485, cannot find original notary document

[mikeynyc]

Hi all - I filed the i-485 using a birth certificate notary (photocopied) and two affidavits. However, now I cannot find the original document of the notarized birth certificate, but of course I have photocopies.
Question:
1) Is this something to be worried about for the interview? Will they ask me to produce the original copy of this notarized birth certificate document?
2) Would I be able to explain that I lost this original document after submitting application?
3) Is it worth it to just try and obtain another notarized birth certificate document from my home country as a precaution, in case they ask? Will this document notarized birth certificate document that is different from the one used in filing be acceptable if I explain the situation?


Thanks so much!
