For people looking to teach English overseas, Central and South America has a huge demand for English teachers. Mexico, Argentina, Colombia and Ecuador all have robust markets.
Compared to other regions of the world where you can teach English, Latin America tends to offer relatively low salaries. To offset the cost of living in most Latin American countries, English teachers are likely to earn more than enough. However, the continent's appeal is primarily due to its diverse geography, easy-going, hospitable people and rich culture, not its wealth.
Higher education is not required, so there aren't many requirements for ESL teachers.
As more and more prospective English teachers move to Latin America, it is advisable to have teaching experience there as well. However, Latin America is still underrated as a destination for English teachers. Depending on your position, you can quickly learn the local language while teaching English to both adults and children, thanks to the range of Spanish and Portuguese study programs available.
