请教老师：现在旧的H1B已经过期，H1B extension 正在pending， 现在需要出境开会再用AP返美，做了一下研究，知道H1B extension pending期间，离境不会让H1B extension的申请作废。我的问题是：
1. 用AP返美后，我的身份是AOS，但是不想使用EAD。我还可以用extension pending的240天为原雇主工作吗？
-I don't think so because after you used AP to reenter US, your status is Parolee, not H-1 holder, though you can use the H-1 benefits if your previous status is H-1 before you left US. In your case, your current H-1 status actually is pending, i.e. not in H-1 status (old I-94 expired, new I-94 pending).
还是必须启用EAD？
-Probably yes.
2. 如果可以不用EAD，等H1B extension批准以后，我的身份可以从AOS自动回到H1B吗？
-Yes if the approval has I-94.
还是要出境重新签H1B签证？
-If the approval has no I-94, you need to go to China to get the H-1 visa if you want to be H-1 holder. Otherwise, may just use EAD to work.
3. 如果必须用EAD，等H1B extension批准以后，我的身份可以从AOS自动回到H1B吗？
-Technically no, but probably USCIS does not care about it that much.
还是要出境重新签H1B签证？
我在网上查了好几天，还是不太确定。所以请老师指教。多谢！
