863211, mylawyer, HongYe,
sorry for late reply because of heavy work.
Thank you all very much for your opion.
For HongYe's concern, most of lawyer said: there is no
rules in immigration law to mention clearly that EAD will disable H4.
Their opnion is pretty same as 863211 and mylawyer's viewpoint.
I also want to know how PiJiang think, well, seems he
is not here? a little regret...
Anyway, thank you all very much for help.
Jerry.
