What do expats find most challenging?

"Expats in Dusseldorf often find the local culture to be quite different from what they are used to. The language barrier can be a challenge, as German is the primary language spoken in the city. Additionally, the local customs and etiquette can be difficult to navigate, as they are quite different from those of other countries. Furthermore, the cost of living in Dusseldorf is quite high, making it difficult for expats to adjust to the local lifestyle. Finally, the weather in Dusseldorf can be unpredictable, making it difficult to plan outdoor activities," remarked another expat who made the move to Dusseldorf, Germany.
