State visits are formal visits to the United Kingdom by Heads of State from overseas.
There are usually two incoming State visits each year.
A State Visit normally last two or three days and start with an official reception at either Horse Guards in London, Windsor Castle or the Palace of Hollyrood House in Edinburgh.
For the State Visit on the 3rd June 2109, when Mr Donald Trump the President of the United States will be a guest of Her Majesty at Buckingham Palace, the official welcome will take place in the Palace Gardens and the Guard of Honour will be provided by Nijmegen Company Gredadier Guards.
Invitations to Foreign Monarchs, Presidents or Prime Ministers are sent on the advice of the Foreign and Commonwealth Office.
State Visits normally begin with a ceremonial welcome attended by The Queen and other senior members of the Royal Family.
If the guest is staying at Buckingham Palace, the welcome takes place on Horse Guards Parade.
The next State Visit is expected to take place between the 3rd and 5th June 2019 with The President of The United States of America, President Donald J. Trump, accompanied by Mrs Melania Trump, staying as guests of Her Majesty the Queen at Buckingham Palace.
Once Her Majesty The Queen and other dignitaries have met the visitor they will normally inspect a Guard of Honour, provided by one of the Battalions or Incremental Companies of the Household Division.
The Captain of the Guard will always present the Guard in the language of the visitor.
After inspecting a guard of honour, the visiting President or Monarch then travels with HM The Queen, by carriage, back to Buckingham Palace with the Household Cavalry providing a Sovereign's Escort.
