A Russian agency is pushing new rules of conduct on Central Asian migrants that severely restrict usage of their native languages and warn them about praying in public and sacrificing animals for religious purposes. Central Asian migrants are told about the strict rules and code of behavior in a 70-minute course created by Russia's Federal Agency of Ethnic Affairs (FADN) in seminars in certain parts of the country. It includes for them to have mandatory knowledge of the Russian language and the country's migration laws, not to use their native language when they talk about Russians, and not to whistle at members of the opposite sex. The course also tells them "not to even whisper" in public using their mother tongue, Kommersant reported. Moreover, the common Central Asian practice of addressing people as "brother" or "sister" is said to be unacceptable when referring to Russians. Along with the language and behavioral restrictions, there are also religious limitations. The slaughtering of animals for religious worship in public will also be prohibited.
