Yes.
如果我在我老婆排期CURRENT後再申請一個485,我能通過這個485再申請EAD嗎?
Yes.
一個人能同時有兩個EAD嗎?
How can you get two? One is be canceled. Even you want to get another one, when you file 765, your information is been put inside.
EAD能TRANSFER嗎?
No.
如果遇到這種情況:需要從一個485過渡到另一個485,那EAD如何銜接?
It can not be connected. It is based on different 485.
