Researching UK entrepreneurs that have secured a US Visa

Writing an article that will profile UK entrepreneurs that have managed to secure a US visa.

It's a continuation from this article http://www.startups.co.uk/what-london-can-learn-from-silicon-valley.html

Looking to quote in the article.

Love to hear from you if this is you - email me: william.channer@gmail.com

Or just suggest names of UK entrepreneurs in the US that I should get in contact with.
