H4 Extension pending, I 94 expired. H1B job loss, please help

My spouse H4 Extension is pending and her I 94 expired in December. The primary H1B might get laid off. Can H4 stay in US for the 60 day grace period?

Hi Anil,
Thanks for your response. But the thread is not providing information regarding pending H4 Extension with expired I 94. Can you please shed some light on that.
