Situated in the centre of Europe, Switzerland is among the OECD countries with the largest proportion of foreigners in the population. This immigration, which is closely linked to the attractive economic situation of the country, has become more diversified over the past decades, with the entry for instance of nationals of the former Yugoslavia. These often low-skilled workers have nevertheless faced difficulties in entering the labour market and integrating into social life. The Swiss migration policy was reoriented in the last few years with the adoption of the Agreement on the Free Movement of Persons for EU/EFTA countries and the recruitment of nationals of third countries focussed on skilled persons. Some efforts are also underway to improve the integration of the existing stock of foreign workers living in the Confederation. This chapter, which analyses the economic impact of immigration in Switzerland, examines the recent actions taken and proposed avenues, in particular in the education and social domains, for taking better advantage of the potential of the foreign labour force.
