Hello Mr./s Pan 123,
thanks for sharing the question with the Wefugees Community.
In the case of special integration services, the period can be reduced to six years. This can e.g. be the case if particularly good knowledge of German is proven or if there is a long-term voluntary commitment to a non-profit organization or an association. The naturalization authority has a certain amount of leeway in deciding whether special integration services are available.
