What do expats find most challenging?

"Expats in Nha Trang often find the language barrier to be the most challenging aspect of the local culture. Additionally, the cultural norms and expectations can be difficult to navigate, as they are often quite different from those of other countries. Additionally, the local cuisine can be an acquired taste, as it is often quite spicy and heavily reliant on fish sauce. Finally, the climate can be difficult to adjust to, as the summers are hot and humid and the winters are mild," remarked another expat in Nha Trang, Vietnam.
