UCLA vs Gatech vs toronto

[spark1989]

Guys,

I've received few admits (all are either RA and fellowship) and these are my top preferences (ordered) as of now.

Georgia Tech

Toronto

UCLA

British Columbia

Few more received and awaiting couple of more...

I'm mainly interested in Machine Learning and Theory. I am an international student and would like to work in US for some time after my phd.

As of now I'm more inclined towards GT coz they are good in ML and very good in theory, but so is Toronto. I'm not so sure about UCLA and British Columbia.

Assume that I get equally good and well-known profs at all these places.

Joining Toronto may create some visa trouble if I want to join some research lab in US. And what about UCLA .What do you guys think?
