Two thirds of the world's population is bilingual to some extent, hence from an international perspective speaking more than one language is the norm rather than the exception. Germany, Bulgaria, Iraq are only a few of the countries where more than one language is widely spoken. This study aims to analyse the socio-demographic structure and second language acquisition (L2) of a sample of Turkish bilingual children living in Germany through a survey with regard to the socio-demographic structure of the Turkish bilingual children, the socio-demographic structure of the Turkish bilingual children's parents, the Turkish bilingual children's opinions about second language acquisition and the Turkish bilingual children's opinions and thoughts about the society they live in and the schools they attended. The sample comprises 120 Turkish bilingual children attending pre-school and elementary schools in Germany. As a result of the findings, some implications and suggestions are made to the parents and the teachers that they should take necessary precautions to make Turkish bilingual children to integrate to the German society and be successful in the society they live.
