This study investigated the correlation between poverty and the economic experiences of undocumented migrant women residing in a community in Gauteng province, South Africa. Through using a qualitative methodology, we present evidence from interviews and a focus group conducted with 20 women who relate their experiences. Adopting a sustainable livelihood perspective, this article presents the biographical profiles of the women and discusses three themes: social capital influences, tapping into human capital skills, and access to financial capital. This article contributes to debates on promoting gender justice and sustainable livelihoods as a prerequisite for poverty alleviation in Africa.
