Does one have to be over 28 years old to work abroad in Africa?

You do not have to be over 28 years old to work abroad in Africa, because there is no clear age requirement for working abroad, but as a labor worker you must be at least 18 years old.

Going abroad, also known as labor export, refers to the labor exporting country (exporting country) providing labor or services to the labor importing country (importing country) in order to seek economic benefits and obtain foreign exchange earnings. Overseas labor services can be said to be an invisible labor trade.
