Original post by Topo15Following on from this, another important thing to consider is your financial situation, which unlike in the UK, can play a role in your admission success (you might already know about this - but I thought I'd jump in, just in case).
Most schools in the US are 'need aware' for internationals, meaning that if you need lots of help with tuition, you are even less likely to get an offer (the standard is already higher for internationals). Getting an offer from a need-aware college is by no means impossible - many colleges still offer full rides for a select few - but it is very competitive.
I believe only five universities in the US are need-blind for internationals - Harvard, Yale, Amherst, MIT, and Princeton - which are all very competitive.
If it's a factor for you, it might be something else worth considering when choosing who to apply for.
