H4 EAD eligibility status

[ravikumar4869]

For instance my situation, I have approved I-140 with my employer and I applied H4 EAD for my wife, If I get layed off and my employer cancels my I 140, can my wife still hold the EAD status and work or her H4 EAD will be cancelled ? and if my H1B transferred to another employer as soon as I get layed off is the scenario ?

Please let me know accordingly !!
