What do expats find most challenging?

"Expats often find the language barrier to be the most challenging obstacle when living and working abroad, as it can be difficult to communicate and adapt to a foreign language and culture. Other challenges may include cultural differences, loneliness, adapting to different working and living conditions, limited availability of personal connections and familiar amenities, as well as dealing with long-distance relationships. Expats may also have difficulty navigating complex paperwork during the relocation process, as well as regulations and taxation laws in their host countries," said another expat in Praia da Pipa, Brazil.
