As a case in point, I have no Bachelor's degree. I have an Associate's Degree and when I mention this, Europeans typically ask "what's that?" As far as I can tell, this two-year degree is primarily an American thing, though other countries are slowly adopting equivalents of it.
The general rule of thumb seems to be that if you need a degree in your home country, you'll need it in another country. My advice? While you're working on getting your first overseas job, get your Bachelors also. For many US jobs, any four year college degree is needed. For many foreign jobs, they'll be looking at what you have a four year degree in. Only research can tell you what your individual situation will entail.
