Research has indicated that resultant cross-cultural experiences from migration are precursors of transformative learning. This study explores transformative learning processes and outcomes for perspective transformation among Nigerian immigrants in Italy and the United States. Multiple-case study and convergent mixed-methods research designs were utilized for this narrative inquiry. Through a narrative analysis of two participants' stories and quantitative analyses of the Transformative Learning Survey questionnaire, results showed that the learning processes such as critical reflection, discourse, spirituality, and dialogue/support--mainly transversed the cognitive/rational and extra-rational domains of transformative learning. Transformative learning outcomes among the participants included acting differently, self-awareness, and worldview shift. The absence of significant differences at between Italy and the US in transformative learning outcomes reaffirms the universality of these outcomes among Nigerian immigrants. A significant contrast emerged in the "Discourse" process, with a higher average percentage in Italy (96%) compared to the US (83%), highlighting a distinct emphasis on communication and experience-sharing in the Italian context. This study illuminates the shared and unique aspects of transformative learning experiences among Nigerian immigrants in Italy and the United States. The study provides a unique perspective on the use of mixed data in the exploration of transformative learning in cross-cultural contexts. [For the full proceedings, see ED665621.]
