even if the US spouse, while filing the I-751 does not provide documented proof of the bon afide marriage...how about in this case EVEN if the immigrant spouse tells his side of the story as you said....in any situation, isn't the burden on the immigrant spouse to prove that he entered the marriage in good faith, and if so, will providing his side of the story without providing proof of a bonafide marriage help him in any way. I thought you're supposed to prove that the marriage was real when filing for I-751.
