Previous state funerals, for example, the one for former South African president Nelson Mandela, have traditionally accepted that the sitting president would bring a delegation of officials to the event.
The White House has announced that Biden has formally accepted the invitation for the funeral and will be accompanied by the First Lady.
The state funeral will take place at Westminster Abbey and she will lie in state in Westminster Hall from Wednesday, 14 September onwards, according to an announcement by Buckingham Palace.
The Queen's coffin arrived at the Palace of Holyroodhouse in Edinburgh on Sunday, 11 September, after a six-hour long journey from Balmoral Castle to the Scottish capital.
During the period of lying-in-state, members of the public will have the chance to visit Westminster Hall to pay their respects to the Queen.
The Queen died at the age of 96 at Balmoral on 8 September.
