US Vice-President Mike Pence is expected to visit Ireland this year.
It is reported dates in early September are being looked by Irish and US officials.
The Department of Foreign Affairs says Mr Pence "has indicated his wish" to visit Ireland this year.
It says it has had contact with the US administration on the proposed visit, but that it remains unconfirmed.
Mr Pence, who has Irish ancestry from Sligo and Clare, was invited to Ireland by the Taoiseach Leo Varadkar in March during a St Patrick's Day event in the US.
The breakfast in March was seen as a significant moment, as Mr Pence has been criticised in the past for his views on LGBT rights.
He has also been an opponent of laws promoting marriage equality.
Mr Pence had said he planned to make a State visit to Ireland back in 2018, again after hosting Mr Varadkar.
Any trip here would likely mean a further meeting with Mr Varadkar, as well as a meeting with President Michael D Higgins.
A possible visit in September would also be his first time in Ireland in an official capacity.
