Oh no... lost the i-94 replacement, interview coming up... HELP!!!

[spicegirl]

I'm freaking out. My Mom's i-485 initial interview is coming up (10/18) and we lost the I-94 replacement (original got lost, I sent the I-102 to get it replaced). I'm quite sure that during my Mom's I-693 doctor's appointment, the doctor accidentally sealed it with all the exam results... I don't know what to do. There isn't enough time to ask for another replacement (plus it's another $320) and I still hope it's in the medical envelope we mailed to USCIS back in July. Unfortunately there's no way of checking this.
The I-94 number is written on the I-130 and I-485 I filed and a photocopy of it is attached.
Should we go to the interview and say all this or request another replacement and reschedule the interview? I really don't want to do this, we've been waiting since July.
Oh man...

If it was really sealed with the medical, it will be with her file and you can ask the IO to check it during the interview. If not, take the receipts of 102 form or copy of the I-94.

thanks, that's what I was hoping to hear. I'm 95% sure it's with the medical stuff (my Mom had it with all the docs going to her appointment and then it went missing. So either the doctor threw it out or sealed it), I scheduled a walk-in appointment for Tuesday to see if they can look in there or at least tell me if I should bother coming to the interview without the original...
I just hope it doesn't make the whole thing last 5 more months
