What do expats find most challenging?

"Expats in Tallinn often find the language barrier to be the most challenging aspect of the local culture. Estonian is the official language, and while many people in Tallinn speak English, it is not as widely spoken as in other European countries. Additionally, the local culture can be quite different from what expats are used to, with a strong emphasis on tradition and etiquette. This can be difficult to adjust to, especially for those who are not familiar with the local customs. Finally, the weather in Tallinn can be quite extreme, with cold winters and short summers, which can be difficult to adjust to for those coming from warmer climates," remarked another expat in Tallinn, Estonia.
