What do I need to know before moving to Johannesburg?

"Johannesburg is a vibrant and diverse city, and expats should be aware of the cultural differences between their home country and South Africa. It is important to research the local laws and regulations, as well as the cost of living, before making the move. Expats should also be aware of the high crime rate in Johannesburg and take necessary precautions to ensure their safety. Additionally, expats should familiarize themselves with the local language, as English is not widely spoken in South Africa. Finally, expats should take the time to explore the city and its many attractions, as Johannesburg has a lot to offer," remarked another expat who made the move to Johannesburg, South Africa.
