回复：再问Pjiang及热心人有关EAD与AOS,

1)如果不延H1,没有AP与EAD,我是否可以以AOS合法身份停留美国直到绿卡批准 (如果没有rfe)?
-You need to keep your job. You can take a leave wthout pay until you get your EAD.

2)如果现在申请EAD 与 AP, 待批准后回国,工作几个月,待485排期当前再用AP回美, EAD工作,是否可行?
-If your U.S. employer agrees you to do that, it is Ok.
3)EAD paper or Efile, 哪个更快?
-Not different.
4)申请expedite EAD 需要什么条件?
-I am not sure.
