Intent to marry when on B visa

Question: Please advise about the best time to get married if you travelling to US on B visa and you are attempting green card?

Answer: Any pre-conceived plan, interfering with the intent of entry, can get such a person in trouble, if discovered. However, a recent update on FAM now puts any action within 90 days of entry revealing an intent, which if contrary to the intent of entry, will get the later filed cases denied.
