Djibouti is a small French- and Arabic-speaking country on the Horn of Africa which borders Somalia, Eritrea, Ethiopia, and has a coastline on the Red Sea. It has a population of less than one million, which explains the lack of demand for TEFL teachers. The government in Djibouti has made education a priority: they have committed over 20% of the country’s GDP to education and so it would be fair to assume that teachers will be welcomed if you can make the right contact; you might try sending one of its educational institutions a prospective CV and covering letter asking about career opportunities. You should check which vaccinations you might need if you are going to live in the country.
