Germany’s federal statistics bureau estimated that 61.4 percent of the 112,211 migrants naturalized last year held on to their original nationality, the Welt newspaper reported.
Of those, 38,707 were from EU countries. The outlet said 99 percent of them became dual citizens. None of the 2,689 Iranians, 2,479 Syrians or 2,400 Afghans gave up their first nationality.
This is primarily because many origin countries have tough procedures in place for those wishing to renounce their citizenship, but also because Germany does not demand this anymore.
