Research background: Immigrant entrepreneurship remains a key issue for researchers, politicians, and policymakers. It has been widely discussed from different angles among various researchers in recent studies ? particularly in Europe. However, there is a lack of studies to present the motivation of the causal relationship between immigrant entrepreneurs. Purpose of the article: This study aims to fill the gap and analyze the causal relationship between the motivations of Asian immigrant entrepreneurs in Germany. Methods: The study was conducted through a face-to-face interview using a predesigned questionnaire from Asian business owners in Germany and the Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach was applied to analyze the data. Findings & value added: The results show that capital acquisition, employment, financial problems in the family, and existence opportunities in the market are the factors that have higher priority, and may highly impact the Asian immigrant entrepreneurial decision. On the other hand, relatives or social networks remain the lowest priority factor that encourages Asian immigrants towards self-employment. The study has also found that entrepreneurship in the family, the state support policy for immigrants, low level of education, unfamiliarity with the local language, and dissatisfaction with the previous job belong to the cause group. However, some of the motivating factors relate to the effect group, such as capital acquisition, opportunity in the market, immigrant community ties or social networks, unemployment, and financial problems in the family. The most affected factor among the effect group is unemployment, while immigrant community ties or social network is the least affected factor. This study includes a novel interpretation of the DEMATEL approach that researchers have not yet addressed; therefore, it is highly relevant for policymakers, especially those interested in migration studies. Finding out the main driving forces behind Asian immigrant entrepreneurs in a developed European nation like Germany and how these drivers affect cause-and-effect interactions between them are the contributions that add value to the field.

Research background: Entrepreneurship and migration are top priorities on many national and international agendas. As a result, entrepreneurship is one of the most popular strategies immigrants use to avoid unemployment in a host country. However, studies lack to discuss causal relationships among key barriers to immigrant entrepreneurs. Purpose of the article: This study attempts to fill the knowledge gap and investigate the causal relationship between the primary obstacles faced by Asian immigrant entrepreneurs in Germany. Methods: A predesigned questionnaire was used in face-to-face interviews with Asian business owners in Germany for the study, and the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method of data analysis was used. Findings & value added: The findings reveal that lack of sufficient financial resources to establish a business, high market competition, and a lack of knowledge of the local language of the host country are the most significant barriers, among others, which may severely hamper Asian immigrant business performance and have a considerable impact on their entrepreneurial decision. At the same time, lack of professional knowledge & skills, problems with rules & regulations, and cultural differences are among the least essential obstacles for Asian immigrant entrepreneurs. The findings show that unfamiliarity with the local language, problems with rules and regulations, cultural differences, and lack of international business experience are associated with the causer category. However, lack of enough capital to establish a venture, lack of professional knowledge and skills, difficulty in access to financial resources, and high market competition relate to the receiver category. This research generates value for policymakers, particularly those participating in migration studies. One of the study's novelties is using the DEMATEL framework for decision-making on barriers to immigrant entrepreneurship in the European context.
