H4 EAD 540 days

HI Mr. Anil,

I have a question regarding the [H4 EAD] 540 days extension.
My wife’s H4 and [H4 EAD] applications are pending approval, will the current H4 EAD be eligible for 540 days extension? The current H4 I94 and EAD expires on 14 August 2025. So if the approval doesn’t come on time, can she get the 540 days extension? Or resign from job?

There is no auto extension without a valid H4 i94.
