Hi Kalpesh, I did refer to the post that you have posted in your answer.
I have a question -
My wife’s H1 was approved on 11/25/2020
Today we received her H4 approval copy and it says it is approved from 8/13/2020(the day H4 extension was filed)
Her EAD approval date says - 6/30/2021.
So now my question is what happened to the days that she worked on H1B status(11/25/2020 - till date) now that her H4 is approved starting 8/13/2020.
From 08/13/2020 (from date when H4 EOS is approved) to 11/25/2020 (date when COS from H4 to H1B was approved), your wife status was H4.
The way I look at this is your wife is still in a valid H1B status as you had done change of status from H4 to H1B which got approved effective 11/25/2020 which is, in my understanding, the last action (occurred after her H4 EOS application which got approved effective 08/13/2020).
Your wife can’t go back to H4 status unless you apply for H1B to H4 COS again. Does that make sense?
Once an applicant submit an application, USCIS has to either reject, deny or approve your application. In your case USCIS approved your H4 extension starting 08/13/2020 (to match with the new start date of your H1B extension) as they do not have any reason to reject or deny and it was a rightly filed application. The H4 EAD approval starting 06/30/2021 doesn’t mean anything unless your wife goes back to H4 status, then she may be able to use it again till it’s validity date.
If you are still in doubt about your wife’s status, please consult your attorney or open a case with Emma, the USCIS chatbot. You may also setup online appointment and visit your local USCIS field office to consult with an office in-person.
You seem to be on H1B at this point. Your change of status to H1B happened before your H4 extension was approved. H4 extension was correctly approved by USCIS so that the gap between 24th September (H4 expires) and 1st Oct (change of status to H1B) can be covered by the H4 extension.
H4 EAD was denied because you are no more in H4 status after 1st Oct’2021.
You can consult your employer’s immigration lawyer in case of further doubts.
