The present study deeply analyses the different perspectives of the immigrants towards their country of destination which results in the categorisation of immigrants as either diaspora or transnationals. It also explores the way in which diaspora and transnationalism begin to swerve in their paths; the immigrant's roots and routes are alike but their standpoints are unlike. The act of crossing nation is shared between the two but the different perspectives of the immigrant enable them to develop distinct ideologies which streams to assorted conclusions such as diaspora or transnationals. The channel of diaspora is brimmed with thorns and speed breakers like loneliness and estrangement, that dwindles the speed of the progressive status of the migrants to authorise their identity and they wander in-between the social spaces influenced by the host community and migrated society. Whereas, the boulevard of transnationalism is suffused with restricted speed breakers like nostalgia; it is a smooth lane filled with opportunities of being in more than one place simultaneously to the migrants and ends in acquiring the global identity by overcoming all the impediments in their lives. The objective of the present study is to identify the distinctions of the two concepts and analyse the different perspectives of the immigrants through the novels Zadie Smith's White Teeth and Colm Toibin's Brooklyn under the light of the conventional assimilation theory and assemblage theory.
