<p>pmsoccerpink:
just to reinforce what psmyth000 said. The concept of transfer basically doesn’t exist in UK universities so don’t look to do that from the US to the UK. </p>
<p>The alternatives are really studying for a year or semester abroad whilst still strictly enrolled with your US university, or becoming an undergraduate in the UK which would mean applying from scratch via UCAS. The second option would mean doing a full undergraduate course unless it is as a second degree, in which case they could well excuse you from the first year (Oxford would do that).</p>
