Funny you asked this while I’m preparing for my cross-culture lesson.
I can write a book about this. So I’m going to narrow down to some most important things.
People in my country are generally very open to foreigners. Partly because it’s our culture to be friendly, and partly because many of us haven’t been to any other country because, you know, financial reason. But please don’t try to be over-friendly like you do in the US. It’s not like we don’t like people who share too much personal information (like what my bullshit textbook claims. Maybe it is right in other regions but I don’t experience it here), it’s just that you can risk creating a false impression that you want to be their friend, even though you only try to be friendly.
There’s one thing I always want to warn any foreigner who wants to visit my country: cheating. Yeah, cheating is everywhere, especially with you foreigners. You can risk buying something for a much higher price than it worths, being charged for something that could have been free, or losing your stuff while you aren’t looking. The culprits are mostly poor assholes who can only speak one language and assume that you do too, and owners of shops/bars/restaurants for foreigners who wants to milk money from you. “Poor assholes” are easy to recognize: they look poor in your American standards and maybe a bit desperate, stand in the street and always appear to be selling something. On your first days here, don’t bring many valuable things with you, and hold dear to your bags/wallets in crowded areas. If you see anyone standing in the street and looking like they are selling anything, walk part them, pretend they don’t exist. Don’t enter shops or restaurants that don’t look so… decent, at least when you still don’t know how to bargain. Wait until you gain more experience before you try anything more daring.
Apart from that, life is pretty easy. Prices here are much cheaper than in America. You don’t have to worry of being broke if you use your money wisely. You can at least afford a decent appartment and good meals. Oh, but you have to learn how to cook for yourself if you want a safe meal. Food in small restaurants aren’t always reliable.
And people are a bit conservative and afraid of being judged. You may have a hard time trying to convince someone to give up their outdated view. Just try to be indirect and soft when you talk to them. In case their heads are too thick, just don’t mind them.
Bonus content: You can be as American as possible with me! My mindset is kind of compatible with your American one and I can understand/tolerate your lack of knowledge about my culture. I’d love to learn more about your culture too, unlike some people here.
Ah! Writing this is much more refreshing than preparing for my lesson :)
