A lot of teachers initially gravitate to Europe as it provides less culture-shock and offers reasonable salaries and working conditions. Europe is fairly diverse when it comes to job prospects and teaching experiences. With the advent of the EU labor law it is now difficult (and is some cases impossible) for teachers who don't hold an EU passport to get working visas in some countries. This doesn't mean that it's difficult or impossible to find work, just to get your official papers in order. However, with the ridiculous bureaucratic requirements, still in place in some EU countries, even EU passport holders give up on getting work visas! It will certainly be easier if you are a citizen of an EU member state but it is not an insurmountable problem if you aren't.
