US Secretary of State Hillary Clinton is due to arrive in Belfast on Friday as part of a four-day trip to Europe.
It is understood she will meet Northern Ireland's first minister and deputy first minister, and attend an Ireland Fund dinner at Titanic Belfast.
It could be one of her last foreign engagements as Washington's most senior diplomat.
Her visit comes amid tensions over the decision to stop flying the Union flag at Belfast City Hall every day.
