Can we keep working on H4 EAD ( based on the receipt)?

My H4 and H4 EAD is going to expire on Sept 30th 2020. My spouse H1B extension got approved for the next 3 years; and my H4, H4 EAD Extension is still in progress. Waiting for biometric notice. I have received h4, h4 ead receipt notice.

Can we keep working on H4 EAD ( based on the receipt) even after September 30th, if my H4/EAD did not get approved before that?

Based on my understanding, you cannot continue working past your expiration date until you get the new EAD card even if you have the receipt.

You cannot work if your current H4 EAD expires and new one is pending approval.

My wife’s H4 797 is valid till 08/16/2020
Her I-94 is valid till 08/06/2020
Her H4 EAD is valid till 08/16/2020

mine and her extension is in progress. How long can wife keep working - upto EAD validity date or upto i-94 validity date , considering extension is already in progress

i went through the article and none of the scenarios mentioned answer my question
kindly help.
