H4 EAD Validity

[Ram89]

Hi,

My wife's H4 EAD is expiring Next year Aug 2020 ( Got this based on my previous employers H1). I changed job last year and got H1 until April 2020 next year

So as my H1 time is shrinked does this apply to my wife's EAD too.

I'm planning for new extension next month and can she work on her EAD until Aug 2020 or April 2020.

Thanks,
Ram
