Experts ! I have been reading something about Advance Parole and travel restrictions and seeking for some clarity here. USCIS website define using AP for "emergent personal and bonafide reason to travel temporarily abroad". Does this mean re-entering US with an AP after a vacation or travel to home country for visiting parents would put us in trouble? (This is assuming I have an expired H1B and have used AC21 to switch employers after 180 days of filing I-485). Can someone please clarify?
