The article focuses on the analysis of the data from the research of the late successive bilingualism, where language learning took place in the natural environment of the host country. The aim is to analyse the following processes: second language acquisition and its common elements; acquirement of bilingual experience and bilingual identity; revelation of specific features typical for bilinguals and self-reflective description of them.
Research was conducted within Russian-Czech bilinguals, whose native language was Russian and the Czech language acquisition was started in the adolescent age. Informants answered questions about the process of the Czech language acquisition and its role in everyday life.
The received data were sort out and analysed using the methods of the qualitative research.
