Many schools at all levels (elementary secondary university and adult education) are seeking teachers who are native speakers of English or have TEFL training. The nation is largely unreached and needs people who can shine the light to come and serve here. English teaching is currently the most accessible job in this country.
Work for an ESL teacher is generally teaching classes preparing exercises and exams grading etc. Often speaking and listening skills are delegated to the foreign ESL teachers particularly. There are lots of opportunities with students plus interactions with parents and school administrators in which the Christian teacher can demonstrate love and show faith at work. These jobs provide a work visa and residence permission plus good-to-excellent compensation.
The requirement for native speakers of English is an undergraduate degree in any subject plus a TEFL certificate. There are various ways to acquire the TEFL certification including taking an inexpensive and short online course. Appropriate experience is valuable but not required. A non-native English speaker should have a university degree in English or Teaching English.
