Ask HN: What is required to hire myself as a contractor in the US?

Background: I live in the UK and very recently I started contracting.

I have my own limited company, bank account, accountant and annual tax returns to fill.

If I'm doing this in the UK, I wonder if it is possible to do the same in the US?

Say - establish Delaware corporation and offer services to businesses located in the US...

I already have a tourist visa allowing me to stay for 6 months at a time...

Has anyone got any idea? (all the feedback appreaciated)

I was in the US twice already and I envy the culture of innovation and entrepreneurship. And obviously the weather in California is much better than in London :)

Getting H1-B (official working visa) is a real hassle, but maybe the is a loophole allowing me to overcome it...

Thank you in advance!
