Question: L2S work authorization

This is regarding my L2S work authorization, can you please help me understand below question-

My L2S and EAD are expiring by the end of March 2023 can I still be authorized to work on the extension receipt/notice?

If Yes - What would be the extension tenure.
If No - Can you please advise.

Thank you for your time and guidance.

You can continue working if your L2 extension is timely filed before the expiry of current I-797.

540 days. Note that L2 do not need to apply for EAD as they are authorized to work by virtue of holding L2.

Thank you Mr.Kalpesh for your time and prompt response. It certainly helped me get some clarity.
