What do expats find most challenging?

"Expats in Johannesburg often find the local culture to be quite different from what they are used to. The language barrier can be a challenge, as English is not widely spoken in many parts of the city. Additionally, the cost of living in Johannesburg is quite high, making it difficult for expats to adjust to the local economy. Furthermore, the city is known for its high crime rate, which can be intimidating for newcomers. Finally, the cultural norms and expectations can be difficult to navigate, as they are often quite different from those of other countries," mentioned another expat when asked about moving to Johannesburg, South Africa.
