Koala, If getting a visa is not going to be an issue for you why don't you see if you can get cross credits for what you have done at La Trobe through an American university and see if that is quicker, plus you'll be in the US and you can sus things out from here. I know work wise you would not have any trouble getting a job as a CNA though the work and the pay can be pretty bad. Its worth a look anyhow.
