The article explores Southeast Asian diasporas' complex histories, experiences, and community formations in the U.S. and Southeast Asian diaspora consciousness which refers to emerging awareness of shared identities, heritages, and experiences of displacement due to migration, exile, displacement, wars, violence, political persecution, economic hardship, and lack of opportunities. This consciousness embodies multiple senses of belonging and unbelonging, emotional ties to homelands, resistance to colonial and imperial dominations and oppressions, cultural/linguistic hybridities and in-betweenness, and the complexities of maintaining cultural/linguistic heritages while navigating cultural/linguistic identities. Focusing on such Southeast Asian diaspora experiences as memories, interconnectedness, healing, and visions, the author examines Southeast Asian diaspora consciousness such as remembering toward imagining and practicing healing; continuities and discontinuities of coexistence, uncertainty, and survivance; intergenerational intertwining; and Southeast Asian diaspora space and place consciousness. Connecting through shared memories, experiences, and struggles, Southeast Asian diasporas invent their shared futures for thriving existence.
