I'm going through divorce; marriage was in Aug 1998 (in good faith), application approved Jan 1999, conditions removed successfully as of Jan 2003 and sadly marriage failed summer 2004. Your divorce should have no bearing whatsoever on your resident status, provided you don't become a "public charge". I have no intention of becoming a citizen just yet, so perhaps my situation is a little different; but as the conditions have been removed successfully, there should be no bearing on your residency.
Edit: I'm curious as to why "good faith" would be so difficult to prove? Proof of this is required not only for the initial application, but sometimes to have conditional status removed too...it implies (to me) that only if your spouse then decides to complain, would it be an issue..and in that case, surely the burden of proof is on him to prove the marriage *wasn't* in good faith?
