my wife is awaiting green card interview for I485 AOS. she finally got an Advance Parole Document (I131) after waiting over a year. Its valid for a year so expires Mar 2024. We'd like to travel to Thailand for 4 months next winter, is 4 months too long for a Advance Parole? I've heard people say you should only leave for a few weeks but that may be just BS. any thoughts? thanks
PS, I know if we get an interview appointment while we are away, we'd have to come back sooner.
