Intercultural aspects are important aspects in software engineering in teaching as well as in practice. In the requirements engineering context, these topics are not so well addressed by research, and if they are, then in the meaning of national cultures. The authors expect that, besides this, the diverse \"Professional cultures\" of the participants in the requirements engineering process are an equally important aspect. This paper provides a first proposal for research collaboration on intercultural aspects in requirements engineering teaching. They are searching partners for this paper.
