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.
