根據您的回複，因為H4 EAD 還有兩年才過期，所以現在不能申請EAD with AOS, 隻能申請AP，那麽AP 和EAD就不是combo card了吧？
-Right. Of course, it does not hurt you to fle I-131 and I-765 together to apply for the EAD/AP combo card, but I don't think USCIS will approve it because your current H-4 EAD will not expire within 120 days.
如果我明年用AP回國，不影響EAD吧？
-No. You still can use H-4 benefit even if your status is not H-4 after using AP. Of ocurse, you also don't need to use AP, but use H-4 visa to come back.
也不用像律師說的那樣用AP travel以後，要update I9 吧？
-Not need unless you use I-485 based EAD..
