What do expats find most challenging?

"Expats can often find adjusting to a new culture, language and environment to be challenging. Working abroad can also be a challenge as workplace cultures and expectations vary from country to country. Navigating the bureaucracy associated with obtaining visas and residence permits can also be a daunting task for expats. Finding housing can be an additional challenge depending on location and circumstances. In addition, expats may feel homesick or experience a sense of isolation due to being away from family and friends. These issues may all be exacerbated depending on how long the expat is away and how their transition is managed," mentioned another expat when asked about moving to Tobercurry, Ireland.
