South Africa is an important destination for immigrants from sub-Saharan Africa. Migration and its impact remain significant in South African society: demographically, politically, economically and socially. Many migrants are forced to take up informal income-generating activities such as day labouring and car guarding. This study investigated the lived experiences and context of reception of foreign migrant car guards using a survey instrument among formal car guards working in the parking lots of shopping centres in the western part of Johannesburg. Demographic data, employment history and objective and subjective indicators were used to assess their socio-economic and labour market outcomes. The subjective well-being of the migrant car guards was analysed using descriptive statistics and an ordered probit model. The study revealed the extent and depth of the vulnerabilities experienced by individuals subjected to working in the informal economy as well as being migrants. They have to tolerate sub-standard employment in the informal sector as there are no other viable options. At the same time, they must provide for dependants back home. The result is emotional stress and low levels of subjective well-being. Migrant car guards' unique labour market status and relationship with the shopping centres and car guard companies deserve urgent research attention.
