Should I stay or should I go?

After spending nearly 8 years in the UK, I have been thinking alot recently about where in the world I'd like to spend the next 8 years of my life. There is nothing wrong with the UK, I've had some very good times here, the job opportunities are good, I'm familiar with the country and culture and they have Jaffa Cakes. All good things. But is it's time up? Am I ready to move on and explore some other part of the globe?

Tonight I went to listen to Anastasia Tonello of Laura Devine speak on UK/US immigration options for Oxford students. She was a very good presenter and although most of the talk was on how to get into the UK, I did get a chance to speak with her afterwards about the possibility of getting into the US.

Basically, it's very hard to get a Work Permit for the US. Really hard. I haven't decided yet if that information has made me want to work there more or not. My best chance appears to be to recieve a job offer from a firm and have them apply for an H1B visa for me.

So, a poll. Should I stay or should I go?
