The experiences of the two are wildly different. Those expectations can include knowing how to entertain, dressing the part, good table manners, and cultural sensitivity with a truly international community that can be more savvy and experienced, according to Montana. That's not just learning table etiquette but also relates to being a good guest in another country. Identity is at the core of the culture shock of expat living and profoundly impacts on that 'expat class system' referred to by Nicole Rosenleaf Ritter. Or not fit, as the case may be.
Nationalities also play a social role.
New expats often find themselves socializing with others from their own countries for no other reason than that they share a flag and find themselves reeling with shock from being with too many fellow countrymen. Griping about local people and customs ironically brings some expats together. For starters, don't think that just because you carry the same passport as someone else you will automatically be friends or indeed have to be friends. Be your own person. Like all forms of culture shock, you must strive for a period of adjustment which means acceptance.
