回複：請教平江老師，關於H4回國

1、可不可以申請了AP，但不用AP仍用H4身份入境？
- of course, it was mentioned in 閑話 AP (I-131) 和 EAD (I-765)

2、在申請了AP但沒使用的情況下，如果以H4身份入境，是不是說必須要等到485收據才能回國呢？
- When you have received AP, you should have already received I-485 receipt as well.

入關的時候，海關怎麽會知道你在申請485呢？一定要帶著485的收據原件嗎？
- Sure they know it, right in the system. It is the original, as stated in Sec. 245.2
