我原来有H1B的配偶H4的EAD，最近先生renew了H1B，我正准备找工作，所以想去renew EAD，先生说现在在讨论要取消H4的EAD，好像拿H4的EAD工作过，会有麻烦，所以他说不要用了，现在马上file I-485, 同时申请EAD，那EAD approve是不是要等3-6个月？
-Yes, it may take 2 to 3 months.
如果我用了EAD，就失去了H4的身份对吗？
-Yes if you use I-485 EAD.
那万一I-140或I-485没被批准，我还可以回到H4吗？
-Yes, but you need to go to China to get the H-4 visa to come back. It is not a big deal as long as your spouse keep his H-1 status.
我4月中要回国一趟，现在同时申请AP，估计也来不及了，所以我就拿H4回去和回来，那现在还要申请AP吗？
-You can apply for EAD and AP when you file I-485, and if AP application is still pending, you can leave and get the H-4 visa to come back, or just go to the local USCIS Office to get the emergency AP before you leave.
会有不好的影响吗？
-No problem.
或者最好回来以后再申请？
