A company filed H1b for my wife(who is on H4 visa with me in US) this year through H1b quota. if H4 visa is expired and if we are still waiting for

If your wife's H-4 visa status is expired and she is still waiting for the H-1B which was filed on her behalf, she would not be considered out of status as long as the H-4 extended until September 30 if your wife is applying for a cap H-1B. Your wife can file for an H-4 extension even after the date is expired, but it will be up to U.S.C.I.S. as to whether it will approve a late extension. As your I-140 petition is already approved, you can think of your wife filing an H-4 EAD, but should be aware that U.S.C.I.S. is reportedly looking to rescind the rule that allows H-4 employment. If you and your wife do decide to go that route, your wife can file for extension and EAD at the same time. If your wife obtains the H-4 EAD before her H-1B is approved and the H-1B is later approved, the H-1B would be valid and supersede the H-4.
