Introduction <p>This study explores the accessibility of healthcare for migrants in Iran, focusing on the challenges faced by approximately 3.8 million migrants. Key barriers to access include legal status, financial constraints, and cultural differences.</p> Methods <p>The research employs a review of documents and semi-structured interviews with 25 purposively-selected healthcare providers—such as government officials, healthcare professionals, and experts from international organizations working in migrant health.</p> Results <p>The research reveals significant disparities in healthcare access. Legal migrants generally receive essential healthcare assistance from the government and United Nation High Commissionaire for Refugees, while illegal migrants typically face high out-of-pocket expenses and difficulty obtaining necessary medical care.</p> Conclusion <p>The study emphasizes the necessity of implementing more inclusive health policies that offer coverage to all migrants, regardless of their legal status, to reduce health inequalities. Recommendations involve enhancing access to affordable health insurance, decreasing treatment costs, and improving cooperation between government organizations and non-governmental organizations (NGOs) to ensure equitable healthcare for all. This study seeks to enhance public health results in Iran by tackling the specific health issues faced by various migrant groups and advocates for broader healthcare policies that emphasize the welfare of every resident.</p>
