Wherever you want to go, teaching jobs are likely available but it is harder to get hired in some places. Western Europe is a tough nut to crack. Eastern Europe has many opportunities as does South America. Still atop the list of areas that desperately need a host of English teachers is Asia. It is tougher to get a teaching job in Hong Kong and Japan but South Korea, Thailand, China and Indonesia offer many opportunities. Be flexible and prepared to go where the jobs are to gain experience.
