US President Donald Trump is planning to invite King Charles and Queen Camilla to the US next year, a senior White House official confirmed to the BBC.
The date of the visit - which will come as the US marks its 250th anniversary - remains unclear.
Trump made a second state visit to the UK this week to meet with the King and Prime Minister Keir Starmer, describing the visit as an "exquisite honour" and a sign of an "unbreakable bond" between the two countries.
The last official state visit by a British monarch to the US took place in 2007, under the reign of the late Queen Elizabeth.
The visit is being planned as a separate event from those celebrating the US 250th anniversary celebrations, according to the official.
