Indigenous people migration to big cities is a current phenomenon in Latin America, which has deeply influenced group and individual ethnic identities (Imilan et al., 2017). In the migratory contexts, individuals develop active or passive roles in the decision to migrate and in the actions that take part of the process (MacDonald et al., 1964; Massey et al. 1993; Solinger 1997; De Fina et al., 2008; Haug, 2008; Gustafson 2014). These roles are reveled in the narrative constructions of migrants with regard to their migratory experiences. The following article aims at analyzing how mapuche people that have migrated from the southern communities of Chile to the capital city of the country position themselves in the narrative constructions of their migratory experiences. Based on a constructivist paradigm, we will examine the themes and genres that emerge in the interaction with a mapuche interviewer. Analysis is based on De Fina and Georgakopoulou (2008) ‘Social Interactional’ approach which recognizes the underlying discursive processes that produce genres and themes typical of a group or community. Results show how mapuche migrants position themselves in their narrations as agents and objects of the migratory process, through the use of varied narrative resources such as orientation, indexation, referencing and authentication.
