Is it a medical RFE ? Do you have a signed proof of delivery document from FedEx or whichever sender you used ? Did you take a snap of the package with the address label of the sender when you shipped ? You can use all of these as proof that you sent it them.

talk to your lawyer with all the proofs.

It’s very difficult to know if they have received or not. Even if they receive it they don’t update sometimes is what I have heard. In my case, they sent RFE but the case status never showed that. Did you use FedEx priority overnight or UPS Express delivery or USPS express delivery?

fedex priority overnight was used. I have the proof of who signed the package

this is for a medical Rfe

@a g You can use that as a proof. talk to the lawyer. May I know which field office was it ?

Albuquerque field office

when I spoke to uscis my case was at nbc

Did the RFE letter said to send to Albuquerque field office ? or nbc service center ?

After 60 days did you raise a service request to know what happened? did you get a response? if you have not got a response from then you can also use it as a proof that you did try to find out what went wrong.

rfe letter asked to send it to Albuquerque. opened 2 service requests but got no response. finally an emma agent told that there was no response received on the rfe they sent.

such a perplexing situation uscis created

@a g I worry these things all the times. But since you have raised a service request it is also a proof you can use. I have a feeling FedEx has perhaps delivered correctly and it is perhaps not their fault. If the address is proper it is highly unlikely FedEx will make a mistake.

Could you please share the link for raising a service request?

@Ishhhh Oh login to your USCIS account. there browse for where to raise a service request. you will find it.
