With a population of approximately 563,000, Luxembourg is a kaleidoscopic of cultures, comprising over 170 nationalities. The country’s continued progress depends largely on the successful assimilation of immigrants. To better understand what constitutes the best integration, the European Investment Fund for Non-EU nationals, together with the Welcome and Integration office of Luxembourg, funded this project.

To direct these discussions were four main guidelines: (1) The quality of services and activities proposed, (2) the organization (3) the availability of the personnel and (4) the utility of the information received. Transcriptions were analysed with the help of NVivo 10. A systematic and reiterative analysis of decomposing and reconstituting the data was conducted following three main steps. (1). Identification in the transcriptions were read in order to identify potential answers to the aims of the research and main categories ...
