In Ho Chi Minh City, private complexes of rental rooms designated in Vietnamese asnhtrọform one of the cheapest housing stocks, targeting the working-class, including internal rural migrants. This article combines the insights of both migration and urban studies to analyze the occupation of thenhtrọthrough the concept of temporariness. It addresses the tensions between present constraints and long-term plans of rural migrants as well as their translation into the occupation of the urban space. The method draws upon observations of rental housing and interviews conducted in two suburban neighborhoods of HoChiMinhCity in 2020 and 2021, with migrants coming from deltaic and coastal rural areas of Vietnam. It is found that thenh trọprovide housing for rural migrants who are in a long-term temporary situation, within a tight urban fabric with scarce opportunities for access to urban land ownership. Informants have moved to the city up to thirty years ago. Both the move and the duration are explained by multiple factors, from economic and social mutations to environmental pressures on the deltas and the coast. Relative job stability and trust-based interpersonal relationships in the city may strengthen over time, encouraging migrants to stay. Nevertheless, no matter how long they remain in Ho Chi Minh City, many migrants perceive their stay as temporary before a projected return to the hometown, where their permanent residence registration remains. The occupation of thenhtrọobserved, their adaptations, and the narratives of migrants reveal the relative nature of temporariness in migration and draw the contours of the spatial footprint of low-skilled rural migrants in Ho Chi Minh City.
