Bladski: It looks as if your question is being hijacked. There are several ways you can obtain a working visa for the UK. The first is as you�ve stated, being sponsored. There are companies who will do so. However, the company would most likely need your stateside experiences to meet their needs � for example, if you have an extensive history of hospitality management training, you could be sponsored here.
The next option is coming here on a student visa attending a higher-education course. Within the context of that visa you would be entitled to work.
You could also gain a post here through a US concern. There are actually quite a few of those advertised in port-of-entry cities, as well as the WSJ and FT.
I wish you every success
