Hungarian citizenship is based on the principle of ius sanguinis, thus a child of a Hungarian citizen acquires Hungarian citizenship by birth. Hungarian citizenship can also be acquired by naturalisation and by registration/declaration. The ius soli principle applies only in cases of abandoned and stateless children.
Hungarian law allows dual citizenship. In this context, Section 2 (2) of the Act LV of 1993 on Hungarian Citizenship states that “The Hungarian citizen who is simultaneously a citizen of another state must be regarded as a Hungarian citizen with regard to the application of Hungarian law.” Hungarian law does not pose any consequences in case of non-registration of the new citizenship or non-renunciation of the first citizenship (such as loss of Hungarian citizenship, criminal sanction or administrative fine). Dual citizenship is allowed without any special conditions.
