I did it in three years because my wife is in china .
I used three diffrent tax accountants did it. They totally told me it is same as single. I wasted a lots money because this reason. you mean you are smart than them. If you are right I think I can got a lots money back. you should know they never come here and no any evidence to apply W7 form except passport.
