This paper analyzes the effect of a recently introduced policy reform on participation in integration courses and on certiﬁed language proﬁciency levels among refugees in Germany. The residence rule restricts initial residence for refugees with a permanent residence permit. Given that treatment intensity varies distinctly across states, I utilize this quasi-experiment and apply a difference-in-differences approach. Using an innovative data-set, the IAB-BAMF-SOEP Survey of Refugees, I ﬁnd that stricter statutory provisions have a positive effect on the probability to complete a language course and on the level of certiﬁed language proﬁciency. The results indicate that this effect is driven partly by spatial mismatch.
