Someone broke into my apt last week and stole my naturalization certificate, U.S passport, all immigration papers and receipts. Once i cancelled everything I called USCIS and asked if me not having the original documents would be a problem. The officer assured me that it wouldn't since I already sent in the copies with the package. She did say that I should walk with the control number for the police report and all receipts for stolen documents that i reapplied for. So i guess you walking with your receipt should suffice as well.
That sucks!
Yea, I called them too and they told me that it would be the IO's call whether to accept the copy and reciept or to call it insufficient evidence.
