This quantitative research describes the values of three ethnic groups in comparison with each other as well as with the native groups. It also discusses the acculturation processes of Circassians, Kurds and Turks in Belgium, Germany and the Netherlands. The first research question, “Do immigrant and native groups have similar values?” shows value similarities of Circassians with the French in Belgium, German and Dutch respondents. They have value differences from Flemish respondents. Kurds and Turks have value similarities with German and Flemish respondents, and they have value differences from the Dutch. The second research question, “What acculturation processes do immigrant groups go through?”, confirms high hard assimilation means of Circassians, and high separation means of Turks and Kurds in the Netherlands. In Belgium, Turks have hard high assimilation means, is unexpected, given that Belgium has been a modestly multicultural country. In Turkey, Kurds and Circassians have high assimilation, and Circassians have high integration means. Contrary to the discourses about less participation of immigrants, research findings reveal value similarities of immigrant and native groups in three countries. The European authorities need to develop participative policies to reduce immigrants’ sense of discrimination and natives’ perception of threat for a peaceful society.
