I haven't looked into it more specifically, but it appears foreigners have pretty good access to education in Finland. You also get by well with just English here. I don't know how indefinite visas can be, but my English co-worker has been in the country since he was a kid, enabling him to learn Finnish well enough to be indistinguishable from a native, and I've understood he never applied for citizenship. Taxes and pricing of commodities are heavy here, but perhaps tolerable for a Korean.
EDIT: Looks like Tinytalon already gave a more insightful response.
