Well if I was in your situation, I woulden't care about Cast and it seems you two yourself don't either (Otherwise you two woulden't be loving eachother). And parents, to give you an example: I don't care what my parents say to me as my parents also are very strict about this cast things, but they also know that I don't give rat's ass on the discriminating thinking and idea of theirs, if I love the girl and want to be with her then I will be with her. It is me who has to spend 75% of my life with a girl I marry, not my parents. I do love my parents and respect them, so I will not choose a girl who is complete out of control and without manners and respects for your family either. But that is not your problem. ;) Study wise I don't know, I'd say it may be better if she finished her study and then you can ask her to apply, and you will be able to help her to come to you, coz till then you are setteled out in US. She will also have more possibility after finishing the course, coz if she left in the middle, then she may have to start all over again.
