I'm under 221g and got my second interview last week. Before my interview they ask me to send my fiance's case information for his misdemeanor. My second interview, they just disclosed it to me and ask me if I would still marry him after all his violation disclosed to me. Then I got approved. Be positive and patient. They won't ask for a second interview if they'll just deny you. You're just under AP of getting your Visa ready in the future.
P.S: it basically base on my own experience. I hope you'll get approved soon. Good Luck
