What do I do?

<p>Hey there, I'm an international student. I want to do biochemistry (along with some amount of economics). I've been accepted to UCSD (which I hear is brilliant for biochem), UCLA, NYU, USC, Brandeis and Boston University (full scholarship). Additionally, I have received offers from Imperial College London, Kings College London and UCL (all for courses I'd love to do).</p>

<p>However, I was wondering how the employability would be in the UK, if i choose to go there, after I finish undergraduation (before postgraduation). Also, I may want to work outside the UK, say in US or Singapore. Would my UK degree be recognized there? I was also wondering if these UK universities had any ties with US universities, possibly for summer internships, exchange programs or research projects. Finally, I don't want my postgraduation to be restricted to the UK. Is it possible to get into a good institution even in the US or some other country for postgraduation, after obtaining an undergratuate UK degree?</p>

<p>Any help is welcome. Thanks! :)</p>
