Don't quote me too much on the details, but it's advised to get a work visa before you get over there. I think the reason is because you have to get it validated stateside, or in the country you're currently considered a citizen of. Therefore, you could go over there on a tourist visa and look for work, but you'd have to go back to your country, with your employer's help/signature, and get your visa changed to a work visa before you can work over there legally.

But like I said, don't quote me too closley on that.
