Abstract Multiculturalism has become one of the key concepts in English studies in recent years. Multiculturalism is closely related to discourses or national or cultural identity. The majority is morally obliged to ensure that minorities are neither marginalized nor forced to assimilate completely to the dominant culture. The research paper entitled The Representation of Cultural Liminality in Second Generation Migrants in Zadie Smith’s White Teeth and On Beauty draws attention towards matters such as social assimilation of immigrant generations, identity crisis, discrimination, predestination, or racism and pictures how the immigrants are separated from their home and need to battle with the troubles of living in an imploded empire. Zadie Smith as a black author describes black experience, rather than as a mixed race writer depicting a multicultural environment. The main characters of the novels are mostly migrants and the metropolitan experience they get in a stepping stone in their assimilation and so their different responses to the metropolis embody possible responses to the experience of immigration.
