State visits

A state visit is a formal visit by a head of state to a foreign country, at the invitation of that country's head of state, with the latter also acting as the official host for the duration of the state visit. Speaking for the host, it is generally called a state reception. State visits are considered to be the highest expression of friendly bilateral relations between two sovereign states, and are in general characterised by an emphasis on official public ceremonies.

Less formal visits than a state visit to another country with a lesser emphasis on ceremonial events, by either a head of state or a head of government, can be classified (in descending order of magnitude) as either an official visit, a working visit, a private visit, or a Guest of Government visit.

In parliamentary democracies, while heads of state in such systems of government may formally issue and accept invitations, they do so on the advice of their heads of government, who usually decides on when the invitation is to be issued or accepted in advance.

Queen Elizabeth II is "the most travelled head of state in the world," having made 261 official overseas visits and 96 state visits to 116 countries by the time of her Diamond Jubilee in 2012. Although she is sovereign of each of the Commonwealth realms, in practice, she usually performs full state visits as Queen of the United Kingdom, while the relevant governor-general undertakes state visits for his or her respective country on the sovereign's behalf. However, the Queen has occasionally made some state and official visits representing one of her other Commonwealth realms.

State visits typically involve some or all the following components (each host country has its own traditions):

The visiting head of state is usually accompanied by a senior government minister, usually by a foreign minister. Behind the , delegations made up from trade organizations also accompanies the visiting head of state, offered an opportunity to network and develop economic, cultural, and social links with industry leaders in the nation being visited. At the end of a state visit, the foreign head of state traditionally issues a formal invitation to the head of state of the nation being visited who at another time in the future, would pay a reciprocal state visit.
