I'm 23 and have been working on my own startup, Socialance, for over two years, while at uni (UK).

It is finally ready to launch and registered as a UK company, but I would like to move to Silicon Valley to live and set it up there, since I really like the place.

Being Spanish, as far as I know I can only go there with a tourist Visa valid for 3 months and can't work, let alone start my own company.

Another option may be to apply for a job, but then I would only be able to work on my startup part-time, which is not what I'm looking for.

I know it can be done, since there are companies that have moved to the valley (e.g. Seesmic), but how have other people done it?

Thanks for your help!
