Why Westerners move abroad to teach
The reasons for choosing to teach English in another country, like Korea, will vary between individuals, as is the case with any job. For some, its part of a long-term career plan, and for others its a valuable albeit temporary experience. For those who do not consider teaching as a long-term career, the profession is a stepping stone for gaining work experience with the added benefits of living in a foreign country, saving money and an abundance of travel opportunities ready for the taking.
