Hi Ezy,

None of the majors sponsor, so you need a green card. I ‘won’ my green card in the green card lottery. Each year, approx 55,000 people are granted green cards in the lottery (formally known as the Diversity Visa). Costs nothing to enter. Be aware of various services masquerading as ‘official’ sites which charge you a fee to apply.

I ended up at United, so it can be done. Best of luck!
