Why might some people not want to work in another country?

I think the main reason people hesitate to work abroad is the language and cultural barrier. Even if you're fluent in a foreign language, small misunderstandings in workplace communication can create real stress. For example, in my UI design work in Shanghai, we sometimes collaborate with international clients, and I've seen how tiny translation errors in design briefs can lead to completely wrong color schemes or layouts. That cultural gap becomes much bigger when you're actually living in another country full-time. Also, many professionals worry about being separated from their family support system - like when my colleague turned down a Singapore opportunity because his parents needed regular care back in Hangzhou. The financial benefits might be tempting, but these practical concerns often outweigh them.
