Officials in London are preparing to welcome US President Joe Biden to the UK for a State Visit next year.
And while a visit to Northern Ireland has not been explicitly proposed, a tour of the UK to celebrate 25 years of the Good Friday Agreement would be bizarre if the Irish American President didn't visit the city, people and region which made the peace process.
The trip could also be the first time King Charles III welcomes a fellow Head of State to the UK for an official visit.
