Migration reshapes cultural identity, social belonging, and consumer behavior. Migrants navigate between heritage culture and host-country cultural expectations, influencing brand preference, product adoption, purchasing motives, and social consumption patterns. This research analyzes identity formation across first-generation immigrants, second-generation descendants, temporary migrants, international students, and refugee groups. Using acculturation theory, identity negotiation frameworks, and hypothetical cross-country datasets, the study explores how symbolic goods, cultural products, diaspora networks, digital platforms, and hybrid cultural identities influence consumer identities. Findings show that migrant consumers adopt hybrid consumption identities that serve cultural continuity while enabling social integration. Factors such as social belonging, cultural stigma, economic mobility, and host-country acceptance strongly shape behavior.
