What do expats find most challenging?

"Expats in Finland often find the reserved nature of the locals to be a challenge. Finns tend to be quite private and may not be as open to socializing with strangers as people from other cultures. Additionally, the long, dark winters can be difficult to adjust to, as the lack of sunlight can lead to feelings of depression and isolation. Furthermore, the Finnish language can be difficult to learn, as it is not related to any other language. Finally, the cost of living in Finland is quite high, making it difficult for expats to adjust to the local economy," remarked another expat in Finland.
