What do expats find most challenging?

"Expats typically find adjusting to a new culture to be the most challenging. Language barriers and adapting to unfamiliar cultural norms can be difficult to overcome. Finding or maintaining a job in a different country can sometimes be complicated due to differences in laws or regulations. Expats can also find it difficult to make new friends and build a support network. Isolation, homesickness, and feeling disconnected from family and friends can also be difficult for expats to deal with. Finally, physical and psychological health concerns can be more difficult to address in a foreign country," mentioned another expat when asked about moving to Milan, Italy.
