Have you got your Green Card yet?
In Australia you might think this is your medicare card, but if you're interested in working & living in the USA it's essentially your entry permit. Lavi Soloway has informed me of the nearing of the closing date for the green card lottery, which is your chance to get one of those elusive green cards drawn essentially from a hat. The USA is now also withdrawing the HIV positive ban on those entering the states which may make a big difference for those affected.
Those who are looking to make it big in the States, or just to live and work there for a while or ever, should consider applying. There is more information here to get you started, thanks also to Lavi.
