看8老师说过，可以申请advance parole, then use approved advance parole to travel.
可是，如果急着回中国，可以在递交了advance parole申请后，但是还没有收到 appraoved AP 之前就离开美国吗？
-No!! If it is emergency, they can go to the local USCIS Office to apply for the emergency AP (bring passport, I-485 receipt notice and the I-131 receipt notice).
谢谢8老师
