As both ncp and I have said repeatedly, Ross seems to invite Indians (when I mean Indians- I am referring to Indian Citizens) pretty late in the review period. Both Nc and I were one of the last to receive invites (and if I am not wrong, Saurabh received his towards the fag end to). I would not worry till about 2-3 weeks before the decision date.
Also, I think there is no point in applying to schools now as almost all the R2 deadlines are done or are in the next couple of days. So instead of stressing out now, just go out and enjoy the weather- cold or warm :D I know it is easier said than done...

pandeyrav, I got my interview invites pretty early and had similar thoughts of applying to some other schools. To be honest, I don't think you should unless there are schools that you are really interested in. If not, sit back and wait or you might just end up spending some money needlessly. nc and dosa got their interview invites pretty late and both got in, so I wouldn't worry.
