This investigation of the intercultural contacts of Dutchmen with Germans describes, what uniformities arise in such cases. The low distance between the nationalities means a hard test for the method: For this work a new construct for the investigation of intercultural contacts was created. That bases on the theories of Esser (general migration theory), Bandura (learning theory), Allport (categorization theory) and Tajfel (intergroup theory). While the general action-based migration theory forms the core of the investigation, the socialpsychological theories are used flanking. The result of that concept founded a question list, with 300 variables. The interview row were analysed primary quantitative, secondary qualitative. The here written results are in a style to understand the regularities without statistical knowledge, too. The detailed work was written as diploma thesis at the University of Duisburg (Germany) using own resources and was marked with "very good" (97%).
