Bona Fide Married Relationship MEANS you actually married rather than court marriage to bring someone to USA. To prove that you married ask your write to take all the photo albums and CDs that you have to the embassy. They do not trust the marriage certificate anymore. Also photo like that of jagya, sindur haleko, kanyadan etc etc are the one they look for. You might laugh but it it the truth. Also another thing your wife might face is that" your husband graduated, he will come back home why do u have to go to US?" Think an answer for that question too. Good Luck and all the best.
