The Johannesburg immigrant population is diverse but disproportionately affected by legal vulnerabilities, including lack of documentation, language barriers, and socio-economic challenges. This ethnographic study involved participant observation, semi-structured interviews, and document analysis conducted among a sample of immigrant women. Data collection occurred quarterly over four years, with participants recruited through community centers and social service agencies. Legal support networks have significantly improved access to legal services, particularly for undocumented immigrants, by providing translation assistance, navigating bureaucratic processes, and offering psychosocial support. The study underscores the importance of sustained engagement in immigrant communities for effective legal support. Findings highlight a need for more tailored interventions addressing specific vulnerabilities among women immigrants. Policymakers should prioritise funding for community-based initiatives that strengthen existing legal support networks, while researchers should extend this approach to other vulnerable populations.
