The purpose of this study was twofold: 1) to identify social roles of English in implementing CLIL in English at universities in Russia and 2) to obtain a wide variety of opinions about the content and methodology of CILL in English at universities in St. Petersburg. In regard to the former, this study performed semi-structured interviews with 33 experts, 18 from social sciences and 15 from ESL/EFL education. Concerning the latter, this study conducted a survey among stakeholders and educators (n = 441). According to the data analysis, were identified four main roles of English: Russian English as a variation of English, English as one of the working languages in Russian multilingual and multicultural society, English as the global language, and English as an investment. Meanwhile, the participants in the survey expressed serious concerns about the quality of English used in the implementation of CILL in Russia. However, it could be possible to find an exact concept of the use of English, which will be appropriate and set new perspectives that may match the outlook of Russian citizens.
