Many European countries have implemented mandatory integration courses for refugees and asylum seekers. While evaluations suggest that these programs can improve short-term economic outcomes, little is known about their effectiveness in promoting social and political integration over the long run. In this paper, we focus on the Norwegian Introductory Program, an intensive policy intervention which requires two years of full-time coursework. To identify the causal effect of the program, we leverage quasi-random variation in refugees' arrival dates during the roll-out period. Although we find positive effects on economic integration, we find that the program did not meaningfully influence social or political integration over the long run, as measured via annual administrative data on residential patterns, union membership, intermarriage, citizenship, and validated turnout in local and national elections. This conclusion is further supported by an analysis of the effect of the program on political and social attitudes. Our findings suggest that while introductory programs may improve refugees' economic situation, mandatory coursework is nevertheless ineffective at promoting integration across other domains.
