I am sorry for the delayed reply. It was quite easy to get visitor's visa for her, for some reason Guy just asked simple questions such as why are you planning on going to USA, and she just answered that "my husband is american citizen" and was given " yes" for an answer, but my wife is fairly young and she witnessed many other people get shot down by women but she was lucky to get to the guy in his 30's who asked her questions, so this particular case played in her favor. Edit: Forgot to add, that when it was my wife's turn for window interview, she was told to get in line , but luckily of having witnessed how even a chinese university professor was rejected by a black lady at the interview window, she faked as she had stomach ache and let the guy get in front of her so she could get to talk to Guy instead, which is i find quite hilarious. Anyways, from reading everyone's replies, I am very thankful to everyone, and I guess we'll proceed with Randy W poster's advice, because if there is a chance they might think it is a fraud, I would prefer to avoid their assumption at any costs.
