The relationship between integration and culture has been one of the main discussion topics. Old and strong cultures are expected to bring segregation. Especially in some Asian countries, which has the oldest roots of a culture, segragation is more common than integration. When the immigrants, who live in developed countries, are observed, Asian groups never seem to be integrated completely, unlike the other groups. On the other hand, it was claimed that if the managers are not Asian, they avoid hiring Asian employees, even though they are more honest. These claims are evaluated and it is seen that the answers are inconsistent, but the dominant cultures have a positive impact on business ethics.
