Proud of his roots in Ireland and the US’ role in brokering the agreement, Mr Biden would likely be keen to visit the island of Ireland to mark the anniversary.
Diplomatic sources said it would be an ideal moment to invite Mr Biden for a state visit.
But there were concerns raised over the level of the celebrations, with the Northern Ireland Executive established by the agreement currently collapsed.
The UK government was optimistic, however, that power-sharing could be back up and running by the anniversary.
Biden's Europe visit — in pictures
UK Prime Minister Liz Truss met the US president at a UN summit in New York on Wednesday, but she was not afforded the White House visit that Boris Johnson was treated to last year, with officials blaming the tight schedule of her trip.
Mr Biden did meet Queen Elizabeth II at Windsor Castle after visiting Cornwall for the Group of Seven summit in June last year, but it did not have the full pomp and ceremony of a state visit.
His predecessor, Donald Trump, received a state visit in 2019.
