Rusbox is an online Russian-language school for foreigners and bilingual children. We help children and adults speak in Russian and keep it in good shape. We work both with Russian-speaking children who live abroad, and with adult foreign nationals who need Russian. Our teachers of Russian as a foreign language help them through entertaining and effective classes for bilingual children on the platform via video link. We help children discover Russian culture and boost their interest in the Russian language. In addition, we organize corporate training for foreigners who need Russian for work. We teach elementary- and advanced-level students.
