An important question. Please reply fast!

I am an international student and want to apply to the USA.
I want to know, if I’m first year at a university in my country, is there a problem to apply as a freshman for enrollment in 2011?
I know that in Princeton I can’t, but what about Harvard, Stanford and Yale? Please respond quickly, as the deadline approaches. Also, if I can apply, will being at university now undermine my chances in any way?

To be perfectly honest, if you haven’t started applying you’re not gonna make it this year. Its not just a short form you have to fill out, especially if you’re applying to Harvard/Stanford etc. there’s more to it.

No, I’ve filled the commonapp and the relevant supplements and almost completed my essays. But I recently came across this:
If you have already started a college or university degree program elsewhere, you are not eligible to apply for admission to Princeton.
So I want to know about the other universities I’m interested in. Any help would be appreciated.

Princeton is highly unusual in that it does not accept transfer students. Most colleges have a separate application process for transfer students, i.e. students who have already completed a year or more of college at another school. The deadlines for transfer admissions are often different, so make sure to check on each individual college’s website for specific information.
