What do expats find most challenging?

"Expats often find adjusting to an unfamiliar culture to be one of the most challenging aspects of their experience. Language barriers and understanding the local customs and expectations can be a steep learning curve and navigating a new bureaucracy in a foreign country can be daunting. Building a social network from scratch can be difficult, especially when dealing with limited resources, and finding a job can be difficult when lacking local contacts in the job market. Expats may also find it difficult to adjust to the different cost of living from their home country, which can have a big impact on their lifestyle. Finally, distance from family and friends back home can add to the challenge of expat life," mentioned another expat when asked about moving to Tromso, Norway.
