<p>I’m not sure an access course is a realistic option for an international student. Most colleges* which offer access courses do not provide student accommodation so you would have to rent a flat privately, I image it would be a very isolating experience. If the OP’s American qualifications are not sufficient for Oxbridge then perhaps consider taking a level 2 or level 3 course with the Open University*.</p>
<p>*In the UK a college isn’t a degree awarding institution; they’re more like big high schools in case anybody was wondering.</p>
<p>*The Open University is a highly respected university which offers courses and full degrees via distance learning, all online.</p>
