The general period of residence that must be fulfilled for naturalization is five years. In the past, it could be shortened by up to two additional years in the case of special integration achievements, for example in work, school or voluntary work. This meant that naturalization was possible after just three years of residence. However, the Bundestag decided on 8 October 2025 to abolish naturalization after three years. Naturalization after three years with special integration achievements is therefore no longer possible.
