In this article, we explore the beliefs, values and attitudes about female genital mutilation in the diaspora of sub-Saharan women and how the migration process has influenced these beliefs. Our qualitative analysis of the life stories and lifelines of 10 women in the sub-Saharan diaspora in light of the Social Convention Theory indicated that making public statements about the topic is complex and that the taboo permeating the practice remains intact even outside of Africa. Furthermore, we discovered that, in our context, this practice was not a requirement and did not improve the chances of marriage, with female behaviours considered ‘appropriate’ instead gaining value. Any interventions based on this theory must consider the broad networks that help shape marriages in this diaspora. This work opened new lines of research regarding the situation of the diaspora of sub-Saharan women and the relationship of the practice of female genital mutilation with marriage.
