Prince William is expected to visit the United States next summer for the FIFA World Cup just months after his father makes an official state visit.
The King is expected to visit America next spring ahead of the 250th anniversary of the US Declaration of Independence.
Advanced talks are ongoing for the trip to take place in April, which would mark the first US visit from a reigning British monarch in almost 20 years.
The last state visit to America was made by the late Queen Elizabeth II in 2007, accompanied by the Duke of Edinburgh, following an invitation from President George W Bush.
The Prince of Wales is likely to head stateside next summer for the FIFA World Cup, to be held across the US, Canada and Mexico in June and July, as part of his role as president of the Football Association.
It is the first time the three nations have jointly hosted the championship. England's third group match is scheduled to be played in New Jersey on June 27, one week before the 250th anniversary of US Independence on July 4.
The visit could be timed to ensure the Prince of Wales is still in America during Independence Day, The Times reports.
The royal visits come at a crucial time in relations between the UK and US, as trade negotiations continue following Donald Trump's official visit last September.
During that visit, it was announced the US planned to invest £31 billion in British tech—regarded by ministers as a major victory.
However, the US halted the promised cash injection amid frustration over online safety regulations, digital services tax and food safety legislation. The US has demanded access to the UK market for its farmers, an issue which has proved highly contentious.
Diplomats are said to hope a double-pronged charm offensive from the royal family can help keep the special relationship intact.
Outbound visits from British royals tend to have fewer political pitfalls than receiving US presidents during state visits, and the government is understood to hope both visits can be used to seal a full US-UK trade deal with Trump.
The trade deal must be secured as soon as possible next year, before the president shifts his focus to campaigning for the American midterm elections in November.
Keir Starmer is not thought to be accompanying the King on his visit, with Foreign Secretary Yvette Cooper attending on behalf of the government.
For the 200th anniversary of US independence in 1976, the late Queen and Duke of Edinburgh visited Philadelphia, Washington DC and New York for a six-day trip. The royal couple attended a White House state dinner hosted by Gerald Ford.
In her Christmas broadcast that year, the Queen said: "This year we went to America to join in their bicentennial celebrations. Who would have thought 200 years ago that a descendent of King George III could have taken part in these celebrations?
"Yet that same King was among the first to recognise that old scores must be settled and differences reconciled.
"The United States was born in bitter conflict with Britain but we didn't remain enemies for long."
