End of tenure
When a permanent representative relinquishes his post, the current practice is that he pay a farewell visit to the Director-General of the United Nations Office at Geneva and to the directors and/or secretaries-general of the specialized agencies and other international organizations to which he is accredited and that he inform other permanent representatives, in writing, of his departure.
The United Nations Office at Geneva correspondingly informs the Permanent Mission of the host country. Attention is also, mutatis mutandis, drawn to the section above on Protocol upon assumption of office of permanent representatives.
There is no institutionalised practice of farewell gifts from permanent representatives to a departing permanent representative.
