You are totally right that it is more difficult to get a job in the U.S. The reason is simply due to the
work visa application process. However, there are MANY different work visas you can apply for, even with no education. Look into the H-2B visa, Q visa,
J visa, or check up work for a
cruise boat. The key for you is to get legally into the country and start working. Once you are here on a visa, you have much more options.
What you don't want to do is to come here and work illegally. That will only get you into problems.
In any case, going Down Under is not bad choice either:)
