The Australian chick (SPOILERS)
Part of that sleazy deal with Liotta's character was partly her fault, Liotta's character was a jerk, but she put herself in that position. The Australian woman (Claire) should have done things the right way from the beginning, she shouldn't have filed for an extension, Claire should have gone back to Australia when her visitors visa ran out, she could still look for work in America even FROM Australia, she just needed to research how to legally work and live in the United States.
Claire was looking for work illegally in America, her plan obviously was to keep filing for an extension while looking for work and when she hits the big time as an actress then she could live there. That's a naive and risky way to go about it, and it did nothing but get her into trouble and banned from America. All of that was for nothing, it would have been better if Claire had been patient and done things legally, then at least she wouldn't be banned from The States.
