This study aim’s to examine how conceptions regarding culture and ethnicity influence the daily work of personnel in integration projects financed by the European Social Fund (ESF). The method of this study was individual semi-structured interviews with nine persons working in three different projects. The reason why we have chosen these specific projects was because of their work with immigrant participants. Concepts that our study is based on was culture and ethnicity, but also the theory considering in-groups and out-groups. The result of our study shows that the personnel acknowledge the importance of individual adaptation in the work with the participants, but with awareness considering cultural expressions based on their origin. The answers of the personnel also reveal a cultural hierarchy in the Swedish society. We found out that discrimination from employers is mainly based on the immigrant’s lack of Swedish linguistics. The personnel consider the knowledge of language to be one of the most important factors for immigrants when integrating into a new society. Some of the personnel mentioned that cultural prejudices affect their refutation in the meeting with immigrant participants.
