回复：多谢863211，关于EAD我还有一问。

首先谢谢您的详尽回复。我会写信给USCIS要求重发2年的EAD。问题是我现在还在找工作所以不能把incorrect的EAD卡原件寄回去，我可否寄复印件给USCIS？
-No. You need to send the original incorrect EAD back to get the correct one. You may keep the approval notice and make a copy of the EAD. If your new employer agrees to accept the copy of the EAD with the approval notice, you can work. You have the legal right to work now, but you just need to convince your employer to accept the EAD copy and that is all. USCIS will not make you trouble in this issue.
