Abstract. In recent years, numerous studies have stressed the
importance of established migrants helping newcomers access settlement
information. This article focuses on the everyday practices of these
so-called “arrival brokers” in supporting newcomers in their initial
arrival process. The analysis combines the theoretical strands on “arrival
infrastructures”, arrival brokers, and the concept of solidarity. The
qualitative empirical research in an arrival neighbourhood in the German
city of Dortmund shows that arrival brokers support newcomers by sharing
arrival-specific knowledge and by structuring the arrival infrastructure
network. These practices can be attributed to a situational place-based
solidarity. The article shows that using the infrastructure perspective for
analysing migrants' brokering practices helps us understand the transformative
power wielded by migrants themselves in making, shaping, and maintaining
arrival support structures.
