My native language is Russian and I have never met a foreigner who mastered it even after years and years of practice. It is almost unheard of to find a foreigner who can speak and pronounce correctly. Usually it's one or the other. The majority of native Russians spend 12 years learning Russian grammar and still cannot spell right. I find it hard to believe that a non-native speaker could. On the other hand it took me 3 months to become fluent in English at 14 while attending a high school in the US. Another 6 months to lose my accent and by the end of the year i was thinking in English. Being immersed in the culture of native speakers is probably the best way to learn any language. However, overcoming the complexity of a language is sometimes very difficult/impossible.
