Rhine is criticizing the lack of migration agreements. Hesse's Prime Minister Boris Rhein (CDU) has accused the federal government and the special representative for migration agreements, Joachim Stamp (FDP), of failing to negotiate.

Stamp was Minister in North Rhine-Westphalia until June 2022, where he was responsible for, among other things, refugees and integration. The FDP politician should ensure that migration to Germany is more orderly and that returns of rejected asylum seekers work better.
