Eejit- I talked to my friend who lives in Plymouth and was an Au Pair in America for a while about emigrating to the US, and he told me there were four ways to go about it:
1. Be highly educated and basically say you'll be very useful to the US if you emigrate here.
2. Get a job in the US before entering and have your company sponsor you, ie. endorse your application for a visa
3. Start a business in the US
or
4. Marry an American
I hope this is somewhat helpful for you.
