This chapter’s analysis of Portuguese immigrants’ economic integration in Luxembourg (and in particular their entrepreneurial practices) reflects this long history of Portuguese emigration to this country. The first part of the article briefly describes the evolution of Portuguese emigration to Luxembourg and its insertion in Luxembourg’s labour market. The second part seeks to deepen the understanding of Portuguese immigrants’ entrepreneurial activities (an area that, as the latest literature on Portuguese emigration shows, has not so far benefited from in-depth study1) and to analyse the different factors that influence the creation and development of entrepreneurial practices by the Portuguese abroad. A survey conducted in 2012 among Portuguese entrepreneurs in Luxembourg is used for this analysis. ; info:eu-repo/semantics/publishedVersion
