What do expats find most challenging?

"Expats often find language barriers the most challenging part of relocating to a new country, particularly if the language is different from their own. Trying to understand cultural differences and customs can also be difficult, as well as dealing with bureaucracy and paperwork. Additionally, expats may find it difficult to adapt to a new lifestyle, and may find themselves missing people and places from their home country. Making connections in their new environment and dealing with homesickness can be a challenge for many expats," said another expat in Olten, Switzerland.
