Congrats to you UncleB and your wife!!
Actually, I am in the similar situation. Family based petition (FB1).
My current status is F1 and I already submitted I-485 and other supplement documents about two weeks ago and everything is in progress.
I don't plan to continue as a full-time student next semester, however, I was quite nervous about the situation because there seems to be two opposing concensus regarding this issue. According to your wife's case, tt seems that it would be OK not to continue as a full-timer. Any thoughts on my plan? I'd appreciate anyone's input.
Thanks.
Seems like everyone thinks that you don't have to maintain your F-1 status.....except for the officer that interviewed us.
Based on our experience you will be ok if you don't continue school when your case is pending.
Good luck!
