Article 3
Greece admits and declares to be Greek nationals ipso facto and without the requirement of any formality Bulgarian or Turkish (or Albanian) nationals habitually resident at the date of the coming into force of the present Treaty in territories transferred to Greece by Treaties subsequent to 1 January 1913.
Nevertheless, the persons referred to above who are over 18 years of age, will be entitled under the conditions contained in the said Treaties to opt for any other nationality which may be open to them. Option by a husband will cover his wife, and option by parents will cover their children under 18 years of age.
Persons who have exercised the above right to opt must, except where it is otherwise provided in the said Treaties, transfer within the succeeding twelve months their place of residence to the State for which they have opted. They will be entitled to retain their immovable property in Greek territory. They may carry with them their movable property of every description. No export duties may be imposed upon them in connection with the removal of such property.
