Aussie,
Long story, short.......No chance.
You've only got one way of gaining the right to work in the US and that's to get a Green Card and contrary to public opinion, it's not easy to get one unless...
You marry an American citizen.
Immediate family member is a US citizen.
You have quite a bit of cash to invest in a US business.
Your options at the moment: EK or any of the Asia contracts.
Feel free to PM me. Just spent the last 11 years in the US and my other half is a Septic...
