It seems that "I want to have seen you when I was in USA" is not very correct. However, I can see the sentences like:
So I do feel some sympathy for him, some feeling toward him. I want him to have done better than he did. I want him to have worked this conflict through. And he didn’t do it.
First, they want you to have worked in the area in which you are leading.
Still, is it correct to use perfect infinitive with want to address some actions in the past (which din't take place) or is it wrong?
