What do I need to know before moving to Botswana?

"Botswana is a landlocked country in Southern Africa, bordered by South Africa, Namibia, Zambia, and Zimbabwe. It is a relatively safe and stable country with a strong economy and a growing expat community. Expats should be aware that English is the official language of Botswana, although Setswana is widely spoken. The cost of living in Botswana is generally lower than in other countries in the region, but expats should be prepared for the high cost of imported goods. Expats should also be aware that Botswana has a hot and dry climate, with temperatures reaching up to 40°C in the summer months. Finally, expats should be aware that Botswana has a very strict visa policy, and should research the requirements before making the move," remarked another expat in Botswana.
