H4 EAD validity

Hello,

My spouse has H4 EAD and is looking for Job. The validity of the EAD is another 4 months (per my H1B validity). But now if I change my employer does it affect her EAD validity? another question: can I extend her EAD after I move to different employer with my new petition?

There should be an end date on the EAD which is the validity range of the card. As long as you are in status, the card remains active and is independent of primary H1B employer. You don’t have to apply for extension just because you are changing employers but do so if the card is expiring.
