Samy12, you need all of the chats, emails, pictures, copies of passport stamps, marriage certificate, boarding passes, etc. for your application. You don't even know if there will be an interview yet so what are you asking about? They don't interview everyone in Rabat. So if you have fixed the marriage thing, have you sent in your new application yet? This comes first. Then, while you are waiting to hear something, you keep gathering the same type of proof as you used with the application. More emails, chats, pictures, etc. IF they call you for an interview, you bring all of this stuff with you.
Right now, you and your wife need to worry about preparing a good application so hopefully they won't interview you! And an interview will happen approximately 7 to 10 months AFTER they get your new application. So after you apply, just keep gathering the same type of proof.
