This paper draws on participant-observation and a series of focus group interviews with TPS and DACA youth in Northeast Georgia to understand youth activism emerging from their positionality of being "stuck in-between". "Stuck in-between" captures the liminal legal status of DACA and TPS, denotes the feeling of "stuckness" in mixed-status multigenerational families, and foregrounds the profound ways in which place and race intersect with legal, social, and ideological practices of inclusion/exclusion. Underdocumented youth form multiracial coalitions, guided by Black geographies of the region, to challenge imperial borders that criminalise and (re)produce categories of vulnerability. This place in-between shapes underdocumented youth understanding of the world, informed by, rather than in competition with, Black radical visions of themselves and of the place of the US South.
