I have the exact scenario, where I have sent a birth certificate that was requested back in 2014 (Received date: Nov 16,2016). So do all I485 cases with late registered birth certificates get RFEs? Or it really depends on the processing officer? Can folks who have been through this issue advise whether it would be wise to start working on these documents now, just in case an RFE is issued? or wait until the RFE is issued?

This whole thing is making be very restless..please advise. May the original poster of this thread get this resolve and get his GC soon!! Good luck!!
