Pretty well everyone speaks Russian in Bishkek, so it's a good place to have a Russian language program, but the Kyrgyz also speak... are you braced for it?... Kyrgyz! Kyrgyz is a Turkic language, related to Tatar, Uzbek, Turkmen and Turkish. I've download three textbooks to start getting a feel for the language. Thank you, Foreign Service Institute, for making such things available. I probably will not have time to make myself competent in the language, but at least I will have an idea of what it is like.
