When it comes to job opportunities in education, teaching English as a foreign language accounts for more short-term employment opportunities than any other category of work and provides the ability to gain greater knowledge of your second/third… language while you teach.  

Language teaching will also provide you access to people from different backgrounds and afford unique opportunities and cultural experiences.  There are a large number of international schools that have surfaced in support of multinational organizations (NATO is one example), which now provide employment opportunities for English Language teachers and generic/specialist teachers alike.

A quick search of the internet will reveal most of these and provide details where you can submit your CV. Some schemes will employ you as a teaching assistant in state schools, for example, the Council on International Educational Exchange (CIEE) Teach in China and Teach in Thailand programmers.

You don’t need to have a degree in English or modern languages to teach English in another country but a degree level education will certainly open more doors.
