This study investigates the motivations behind TikTok content creation among Vietnamese Gen Z expatriates by
exploring the interplay of the social comparison theory and the Uses and Gratifications Theory in shaping their engagement with
the platform. Through qualitative interviews, we uncover the dual role of TikTok in their lives: a tool for fostering social
connection and personal expression and a platform for social comparison and validation. These findings illuminate the complex
interplay between digital media use and the experience of digital migration, highlighting how Gen Z expatriates navigate
transnational identities and seek belonging in an increasingly interconnected world. The study contributes to the ongoing
discourse on digitalization and expatriation, emphasizing the multifaceted role of social media in shaping the experiences of
young migrants in the digital age.
