My timeline: premium processing with H4 extension RFE

3/20/19: Case Received. H1, H4, EAD filed concurrently via premium processing (Nebraska Service Center)
3/27/19: H1 approved
3/27/19: RFE for H4 extension (missing marriage certificate)
4/3/19: RFE response received
4/15/19: New card is being produced

No status on H4 but I’m guessing its approved. I was really worried that USCIS would put H4 and H4 EAD into normal processing time.

H4 approval should be on the way too. Do not worry.

Thanks Anil. Appreciate all the helpful responses you have provided.
