H1B at Nebraska - Receipt not received yet

Friends,
My employer has filed new H1B Cap exempt under premium processing at Nebraska on Sep 25th and fedex tracking shows delivery on Sep 26th. It’s been more than a week but not received receipt notice yet. Normally for premium we expect receipt number in email but still not received any email.

Anyone is in the same situation?

Well, sometimes, it can take long…In general, it is quite quick, but can happen. Your employer can reach out to USCIS and follow-up.
