THE CHAIRMAN OF THE HUNGARIAN DELEGATION
Budapest, 24 August 1957
Mr. Chairman,
With respect to the Convention between the Union of Soviet Socialist Republics and the Hungarian People's Republic regulating the citizenship of persons having dual citizenship, signed today, I have the honour to inform you that, in accordance with Hungarian legislation, persons resident in the territory of the Transcarpathian Region of the Ukrainian Soviet Socialist Republic, irrespective of their national origin, who acquired Hungarian citizenship owing to the integration of the territory of the Transcarpathian Region with Hungary in 1939, are not considered Hungarian citizens, inasmuch as, under the Peace Treaty of 1947 and the legislative enactments based on the Peace Treaty, these persons ceased to be Hungarian citizens unless they were resident in the territory of the Hungarian People's Republic on 1 January 1948. Accordingly, the Convention signed today does not apply to these persons.
I have the honour to be, etc.
Sik Endre
