Presentation of credentials

Upon arrival at their post, the ambassador-designate meets with the foreign minister to arrange for an audience with the head of state. They bring both a sealed original and an unsealed copy of his credentials. The unsealed copy is given to the foreign minister upon arrival, and the original is presented personally to the head of state in a formal ceremony. Ambassadors do not begin their duties until their credentials are accepted, and their precedence within the diplomatic corps is determined by the date on which the credentials were presented. They are, however, entitled to diplomatic immunity as soon as they enter the country. The ambassador-designate travels to the presentation ceremony in an official vehicle provided by the receiving state, accompanied by a military escort. In

When a Commonwealth nation is a republic, high commissioners are dispatched and received with letters of commission, which are written by one head of state and presented to another head of state. Both forms of letters were standardized in 1950–1951 after India became a republic, replacing a chaotic system where some high commissioners carried letters from the prime minister, some carried letters from the minister of external relations, and others carried no letters at all.
