What evidence do I need to show concrete proof that my marriage is true and not fraudulent at my upcoming interview at the American Embassy....Would some pictures of my wife and I together with very little clothing on in bed or in a hotel room show help as well as our regular photos that i will be bringing
Your best evidence would be proof of communication over an extended period of time - emails, phone records, Skype sessons - as well as proof of travel together, and evidence of money she may have sent to you, or you to her. Also photos of you two with members of each other's family. Good luck!
