What do expats find most challenging?

"Expats in Puerto Rico often find the language barrier to be the most challenging aspect of the local culture, as Spanish is the dominant language and English is not as widely spoken. They may also struggle with the laid-back attitude towards time, known as "island time", which can be frustrating for those used to strict schedules. In Ecuador, expats may find the cultural differences in personal space and physical contact to be challenging. Ecuadorians tend to stand closer and touch more often during conversations, which can be uncomfortable for those from cultures where personal space is highly valued. Additionally, the slower pace of life and the bureaucratic red tape can be frustrating for expats used to more efficiency," mentioned another expat when asked about moving to Puerto Rico, Ecuador.
