I’m posting this message just for sharing a kind of denial case. @Anil, welcome to comment on.
I was laid off my company on 12/20,2018. On 1/16,2019, I filed H4 COS in regular process based on my husband’s H1B with expiration date of 8/31,2019.
On 3/13,2019, my husband extended his H1B so I also submit H4 extension, which was approved in premium process with validity from 9/1,2019 to 8/30,2022.
On June 10, 2019. My first H4 COS through regular process was denied with the reason that they found there is a H4 has been approved and assume I has been on H4 so they can’t give me another H4…but USCIS didn’t check the approved H4 effective date and just blindly rejected my case…
Solution: my husband’s attorney filed another I539 and NPT for me to cover the date through 8/31,2019. It’s still pending. Will update as I receive the result.
