“…Studies on local legislative bodies might be interesting, as they can play a key role in advancing urban policies in support of irregular migrants (for example, in the case of Zürich, Kaufmann and Strebel 2020). Additionally, immigrant-serving NGOs play a crucial role in pushing policy making in this field (see, for example, Kaufmann and Strebel 2020;Mayer 2018, Spencer 2020); however, there is no reliable comparative city-level data that represent this activity. Case studies could accompany our comparative research to account for in-depth and pathdependent policy-formulation processes, as we only compare these policies in space, not in time.…”
