What do expats find most challenging?

"Expats in Santorini often find the language barrier to be the most challenging aspect of the local culture, as not everyone speaks English and the Greek language can be difficult to learn. The slower pace of life, known as "Greek time", can also be a challenge for those used to more punctual cultures. Additionally, the high influx of tourists during the summer months can make the island feel crowded and less authentic. Some expats also struggle with the lack of diversity and the insular nature of the local community. Lastly, the bureaucracy and red tape involved in dealing with Greek authorities can be frustrating for foreigners," mentioned another expat when asked about moving to Santorini, Greece.
