Despite a rich literature on the factors influencing the public opinion on immigration, less is known about the top-down effects of political parties and policies on the public’s preferences in this domain. We analyse in this paper the impact of political parties’ positions and of immigration policies on citizens’ attitudes toward immigration. We are interested in the effects of public policy understood both in terms of policy regime, that is, country specific regulations on immigration, and policy outcomes, such as the stocks of immigrant population. The results we obtain, based on data covering twenty-three European countries during the period 2002–2011, point to the existence of top-down influences on citizens’ immigration attitudes.
