The objective of the article is to ethnographically describe the social impacts of anti-migratory hate speeches in the Brazilian city of Foz do Iguacu (in the triple border of Parana). We analyze the current Brazilian political context by investigating the present impact of the imaginations of militarism, disseminated on these borders since 1970. We use an ethnographic methodology, with 60 qualitative interviews and a focus group with 11 participants (international migrant students, teachers and technical staff from the University of Latin American Integration). The results show that xenophobia was converted into official discourse in Brazil, articulating statements that advocate intolerance towards minorities and vulnerable sectors. This particularly affects Foz, given the border and military configurations of the city. Likewise, the study allows us to conclude that both speeches and xenophobic practices are articulated by racist imaginary that most strongly impact migrant women.
