There was a referendum in Hungary in December 2004 on whether to grant Hungarian citizenship to Hungarians living outside Hungary's borders (i.e. without requiring a permanent residence in Hungary).
Ungarn afholdt i december 2004 folkeafstemning om hvorvidt, man skulle bevilge ungarsk statsborgerskab til ungarere bosatte uden for Ungarns grænser uden at kræve permanent ophold i Ungarn.
