Background: Immigrant entrepreneurship (IE) has emerged as a vital component of Sweden's economy. However, Vietnamese Immigrant Entrepreneurs are playing an increasingly prominent role in the country's financial landscape, but there seems to be an underexplored research gap. The influence of cultural, and national heritage on financial decision-making specifically towards the Vietnamese Immigrant Entrepreneurs is an underestimated topic, as many entrepreneurs come from backgrounds where their expertise was cultivated, enabling them to operate uneffectively in the financial sector. This paper examines the impact of cultural and national aspects and other characteristics on the financial decision-making of Vietnamese immigrant entrepreneurs. Purpose: This thesis investigates how the cultural and national characteristics influences the financial decision-making of Vietnamese Immigrant Entrepreneurs in Sweden. The research aims to comprehend the impact of cultural values and societal norms of the home country, and its influences on their financial strategies and its process made by these entrepreneurs. It offers profound insight on how cultural identity, cultural background and cultural legacy impacts their entrepreneurial endeavor, specifically in the financing scope. The primary objective is to provide information that can contribute to the academic and practical world. Method: This research uses a qualitative methodology that combines exploratory and interpretative design with relativism ontology, interpretivism, social constructionist epistemology, and an abductive approach. Six Vietnamese IEs who are employed in Sweden were the purposive sample, chosen according to certain sampling criteria, and semi-structured and e-mail interviews were used to collect the data. In order to find, understand, and interpret significant themes and patterns in the transcripts and interviews, the data was further examined using a thematic content analysis. Conclusion: The findings demonstrate the fact that the national and cultural aspects of the Vietnamese IE’s have a significant influence on their financial decision-making in their entrepreneurial endeavor. Their trust and familiarity in informal networks and financing sources, and deeply-rooted risk-averse attitudes in financing based on history and culture exerts aprofound effect that ultimately shapes their financial strategies towards informal financing over formal financing. Furthermore, this research emphasizes the importance of culturally responsive financial products and services in effectively assisting immigrant businesses. Moreover, it emphasizes the significance of comprehending the cultural subtleties that influence financial conduct, hence fostering enhanced economic assimilation and achievement for immigrant entrepreneurs.
