I am a PhD student about to graduate from a university in Western Europe, and recently I have received two postdoctoral job offers - one in Beijing and another in Los Angeles, and I find it hard to choose between them. Thing is, there are faculty I can easily collaborate with in both institutions - therefore, since the teaching load in Beijing is lower (and the pay is higher) I tend to prefer choosing it over Los Angeles.
However, my supervisor (and also several of my colleagues) told me that as far as my academic carreer is concerened, it's better for me to choose Los Angeles. The reason (according to him) is that no one will take me seriously after a postdoc in China, and whatever collaborations I will do there would likely be ignored - it sounds to me pretty extreme (and unreasonable), and I was wondering whether it is true or it is just some bias I should ignore. I do plan on attempting an academic carreer and applying for a permanent position after this job, and more specifically, I would prefer a permanent job in Western Europe (due to family considerations). Is it true that a postdoc position in China would ruin my chances of landing a permanent position in Europe or North America? It sounds pretty extreme and unreasonable to me, but I don't know what to think.
If it matters, my field is Applied Mathematics. Thanks in advance for every reply...
