USA vs UK for IB

<p>Firstly,i am from Central Europe.
At the moment i have high chance to be an undergrad at a target school in UK(LSE,UCL or Warwick) with 2 semi targets as backup plan.
If the targets rejects me then it will only make my path to IB a little more inconvenient to say.</p>

<p>I'd much rather opt for USA.
What are my choices?Can i enroll in a community college like americans do ,work hand and then transfer to a target/semi-target?Or go to a non target university in USA and then transfer?Were can i find more detail about this?(keep in mind that i am not american)
I know that its a little harder to break into IB FO in US.</p>
