Thank you ExponentialDecay! This is extremely helpful and exactly what I want to know. Yeah, I've heard of the 1980-90s Russian emigrants taking academic position thing. It seems like at present the old are in their 70s and the most promising ones are stuck on the level of lecturers. I'm not thinking about Stanford, as it is too Russian-centric, neither Yale and Princeton. Berkeley might be a good option.
If Slavic does not work out well at the end, alternatives may include East European anthropology or history, but I'm more toward a humanity/literature-oriented program, so maybe something like yiddish studies or comp lit. Yet, I assume comp lit program is way harder to get in than area/language-specific literature program as people from all language background are applying at the same time. Is that right?
For the job prospect, I was saying that I was not concerned about or mentioning it in my previous post, and I'm not one of those business/market-oriented people. Plus it is something to worry about a decade later, I just do what I like to pursue at this point of time and regard it as a pure enjoyment of knowledge and humanity. Being a professor is ideal though, the worse scenario would be absolute joblessness in Academia and I can work as something else and become an independent scholar, writer, translator or language tutor to accommodate my interest and make some contributions, or perhaps taking advantage of my education I can move to Europe to find interesting things to do. Idk yet.
