Long story short, my husband wants to go home to his country for a bit but we don't have his AP or Green card yet. I know that if he leaves without receiving either, we are abandoning the AOS application altogether. If in the future he wants to come again, does that mean we have to fill out the I-130 form and start all over? The weird thing would be that we have a marriage license from the US. Not sure if that would make a difference or not. Thank you.
