H-1B RFE issued July 6 but still not received — has anyone dealt with this?

USCIS says an RFE was issued on July 6 for my H-1B, but my employer’s immigration attorney still hasn’t received the actual notice.

My attorney has contacted USCIS, including the Premium Processing Unit, and submitted an inquiry for the missing RFE. The latest update they got was basically that USCIS is reviewing the request and will get back to them, but we still don’t have the notice.

I also called the USCIS Contact Center myself. Since I’m the beneficiary, they wouldn’t give me any case-specific information. But the representative told me that the petitioner or attorney can call USCIS about the missing RFE and that USCIS can email them a copy within 24 hours if the request has been pending for over 7 days.

I also spoke with another immigration attorney separately, and they said that since the case is under premium processing, getting a copy of a missing RFE should usually be easier through the premium processing channel.

So I’m a little confused about why we’re still waiting for USCIS to process the inquiry instead of just getting an emailed copy.

Has anyone dealt with something similar, especially for an H-1B under premium processing?
