Ho Chi Minh City is among the top cities in Vietnam with a high
proportion of rural to urban migration. This strongly contributes to the economic growth of the city but challenges the infrastructure, social security services, health care, clean water, education, traffic, safety, and social order which negatively impacts the quality of life. The purpose of this study was to explore the life quality of rural to urban migrants in Ho Chi Minh City. A quantitative method was employed to confirm the measurement model and structural model. Probability sampling was applied for the field survey. The final data of 272 migrants have been analyzed, using Partial Least Squares Structural Equation Model (PLS-SEM). Social capital, a special resource of the vulnerable like rural to urban migrants has been investigated. This contributes to the theory that both social capital and quality of life have been approached multi-dimensionally. Bonding, bridging, and linking dimensions have all been approached to construct the social capital measurement model. Five aspects of life quality including work, housing, environment, finance, and social cohesion have been measured to reflect the quality of life multi-dimensionally. The research results showed the reliability and validity of the measurement model. The positive impact of social capital on
quality of life has empirically been confirmed. The findings implied the prompt strategies for mobilizing social capital effectively and efficiently, including the exploitation of bonding, bridging, and linking to improve the quality of life
