Western European states have increasingly linked immigration and welfare policy. This trend has important implications for European welfare-state trajectories, but accounts of the policy reasoning behind it have diverged. Are policymakers attempting to delimit social citizenship to secure welfare-state legitimacy? Pursuing new, market-oriented welfare-state goals? Symbolically communicating immigration control intentions to voters? Or attempting to instrumentally steer immigration flows? These accounts have rarely been tested empirically against each other. Redressing this, we employ 83 elite interviews in a comparative process-tracing study of policies linking welfare provision and immigration status in Germany, France, and the UK during the 1990s. We find little evidence suggesting welfare-guided policy reasonings. Rather, this policy linkage appears “immigration-guided:” meant to control “unwanted” immigration or resonate symbolically in immigration politics. Differences in exclusions from welfare support for migrants grew from existing national differences in welfare-state design and politicizations of immigration, not from policy intentions, which were largely shared.
