This corridor report analyse on a comparative basis the integration patters of Ecuadorian and Moroccan immigrants in Spain. The goal of this report is to understand the role of origin countries and societies in integration of these two immigrants communities in Spain. Following the INTERACT project’s idea of “integration as a three-way process”, the report will analyse integration of Ecuadorians and Moroccans in Spain not only from a countries of destination perspective, but also from the point of view of countries and society of origin. To do this, we apply a methodology joining three different type of original sources: a legal and political framework analysis both in origin and destination, a quantitative analysis on some specific integration dimension (labour market, education, and citizenship), and a survey on civil society actors. The analysis conducted emphasizes that historical and political ties between the country of origin and destination may play a role in some specific dimension, as labour market and access to citizenship, through bilateral agreements, and education, through language. In particular, in case of Ecuador bilateral agreements seems to be central in facilitating the integration of immigrants in these Dimensions.
