Not just the U.S. but in most cases, short of a Masters degree or equivalent, it's almost impossible to get hired in another country (some countries have easier migration treaties). Even then it will be difficult. You might be able to come into the U.S. under an H1B program, but there are down sides there.

I'm in the US and have looked into moving overseas in the past. Good luck, I wish I had contacts that could help/share, I just don't.
