Former US president Barack Obama is expected to accept the Freedom of Dublin at a ceremony in the Mansion House this week.
Details are being finalised but it is expected that he will receive the honour on Thursday ahead of an event he is taking part in on Friday.
Mr Obama and his wife Michelle had been invited to accept their Freedom of the City of Dublin.
Lord Mayor of Dublin Ray McAdam said the couple were conferred with the city's highest civic honour in February 2017 by Dublin City Council, but have not had the opportunity to formally accept it.
The Freedom of Dublin would give them a number of entitlements, including being able to graze sheep on St Stephen's Green.
In a letter to the Obamas, Cllr McAdam urged them to come to the Mansion House to accept the honour, saying it is "a rare distinction reserved for individuals whose leadership, service and values have made a profound and lasting contribution to the world".
"As you return to Dublin, I know that many here continue to hold fond memories of your visit in the spring of 2011.
Watch: Obama appreciates seriousness of Freedom of Dublin, says Lord Mayor
"There was a palpable sense of excitement and pride in the city, especially on that unforgettable evening when you addressed the crowds at College Green. It remains one of the defining moments of modern Dublin's story - a moment of shared hope, friendship and global connection," Mr McAdam said.
"The people of Dublin have long admired your leadership, your commitment to public service and your shared belief in the power of community, equality and democracy. It would be a great honour to formally welcome you both as Freeman and Freewoman of our city."
Michelle Obama, who was also awarded the freedom of the city, will not be in attendance to accept her award.
Cllr McAdam said he realises that a number of current councillors have objected to the decision to award the freedom of the city to Mr Obama, but that he is honouring a decision that was taken by the council a number of years ago.
"What I'm doing is ensuring that the will of the elected members that made the decision back in 2017 and 2018 is honoured," he said.
"My job as Lord Mayor and as the chair of Dublin City Council is to ensure that the will of the elected members has followed through. And given that President Obama is going to be in this city this week, it is imperative that I provide the opportunity for him to receive our highest civilian award."
Former US presidents Ulysses S Grant, John F Kennedy and Bill Clinton are also past recipients of the Freedom of Dublin.
Only 88 people have been conferred with the Freedom of Dublin, with the most recent recipients being environmentalists Duncan Stewart and Greta Thunberg in June 2023.
Others include Nelson Mandela, Mikhail Gorbachev, George Bernard Shaw, U2, Brian O'Driscoll and Dr Tony Holohan.
