May be, May be not....
This is not an advise. After I talked to a few lawyers this is what I found out. Everyone has different opinion, but, bottomline is don\'t mess with INS, especially now. One lawyer had a client where she filed for AOS, in a few months her husband did CP. Once it was
successful, immediately they sent a letter to INS to cancel the wife\'s case. This was the client\'s choice not the lawyers.
IMHO, if you are perfect with your paper work, don\'t worry about CP. Once you are there at consulate for CP, I don\'t know if AOS of spouse is useful anymore.
