This study aims to analyze the underlying factors and barriersinfluencing undocumented adults' access to healthcare in Sweden. By focusing on the experiences of five respondents associated with the Swedish Red Cross, the essay seeks to shed light on and enhance the understanding of the limitations faced by undocumented adults, regarding their access to healthcare in Sweden. This study has a qualitative research approach with semi-structured interviews. The studyaddresses three theories for understanding the factors and barriers that affect the access to healthcare by using Goffman (1963) stigma, Young (2011) social justice and Rothstein (2003) trust and social contract theory. The result of the study shows insights information from five respondents of the factors affecting undocumented adults' healthcare access in Sweden. The study ultimately reveals that stigmatization, trust, fear, and social networks are underlying factors that impact the access to healthcare for undocumented adults in Sweden. Additionally,socio-economic barriers are identified as limiting the opportunities for undocumented adults to access healthcare in Sweden. The research highlights that these challenges are not merely individual choices or priorities but rather a result of complex factors and structural impediments. Therefore, addressing the obstacles and underlying factors requires a collective approach to observe and understand the root causes affecting the access to healthcare in Swedenfor undocumented adults.
