Angolais a poor country in Southern Africa. After independence in 1975 it entered a civil war which lasted several decades and cost millions of lives and refugees. It has a population of roughly 17 million.
Training adults in English is a priority in Angola, as in many other African countries where the lingua franca is Portuguese and French. On the other hand, English learning is certainly an expensive endeavour for Angolans as English teaching materials are strongly protected by copyright and consequently hard to buy on a mass scale.
The population of Angola is extremely poor and whilst things are slowly returning to some semblance of normality since the ceasefire in 1994, things still have some way to go. Living conditions for teachers are simple and basic and there is a great demand for experienced teachers, especially in the more rural and remote areas where a school can be just the shade under a tree. Depending on the location, electricity is intermittent so lesson preparation should bear this in mind. Crime is also a problem and many foreigners live in specially guarded compounds.
These can be acquired in Angola but take up to several months to process.
Knowledge of Portuguese is useful since few people speak English.
Pay is usually sufficient to support one person. Depending on the school, pay can sometimes be made in local currency with a one off payment made in USD into your account in the US. Much of the teaching work here is voluntary.
Demand for highly motivated and well educated teachers is extremely high in Angola. Not just English teachers are in demand in this country but also teachers of science, pedagogy and other subjects.
Work can be found in childhood development centres (Angolan kids are lively and enthusiastic), high school, university, training college or polytechnic.
The easiest way to go about finding work is to contact aid agencies such as UNESCO or missionary societies.
