H4 yet to approve after H1B Extension petition premium approved!

[Mari]

I filed H1B extension and H4 in normal process on Sep 2017. I applied premium on Dec1 2018, H1B extension petition had approved but there is no change in H4 status at Nebraska. No one has same issue. 

Please share your thoughts and experience. 

Thanks,

Mari

H4 decision under premium is not mandatory when applied H1B in premium processing but it is very unlike that H4 will take normal processing time when applied with H1B in premium processing. Sometimes, though H1B is approved within 14 days H4 approves a day or two days later considering primary (H1B) is approved.
