EU chief Brexit negotiator Michel Barnier will visit Dublin on Monday for talks with Leo Varadkar.
It is seen as a sign of solidarity for the Irish government ahead of an emergency EU summit in Brussels next week.
It comes after the prime minister Theresa May wrote to European Council president Donald Tusk requesting a Brexit delay, with an option to leave earlier if she can get a leave deal through parliament.
A spokesman for the taoiseach said the aim of Mr Barnier's visit was "to take stock of developments in London as well as the ongoing planning for a possible no-deal scenario".
Foreign affairs minister Simon Coveney said he will want to show solidarity but also have "a detailed conversation in terms of Ireland's perspective on the most recent ask from the prime minister for an extension of time."
He added: "Ireland is of course willing to give the process more time, but we like many other EU member states will want to see a plan to go with that to show that there is a proposed way of finding a majority support in Westminster for a way forward."
Asked about Ireland's position on Mrs May's June 30 request versus a possible flexible one-year extension, Mr Coveney said: "We're open to either in truth."
European Council President Donald Tusk said yesterday he was prepared to propose a year-long delay to Brexit pending a deal at Westminster.
It would mean that local parties would have to field candidates in the European elections next month.
The proposed 'flextention' was welcomed by SDLP leader Colum Eastwood, who blamed the derailing of the Brexit process on "ideological intransigence from the DUP/ERG axis at Westminster".
"We have been calling for the British government to revoke Article 50 and create breathing space to reflect on where this process has taken us," he said.
"The flexibility of our European partners, in the face of extreme frustration, has again proven invaluable.
"In the immediacy, it now seems that elections to the European Parliament will happen in Northern Ireland."
DUP leader Arlene Foster MLA said any extension to Article 50 was "unsurprising but unsatisfactory".
"It should not have been like this. Exiting the EU has become chaotic because of intransigence in Brussels and ineffectiveness in London," she said.
"The United Kingdom fighting European elections almost three years after a clear majority voted to leave the EU sums up the disorganised and slapdash approach taken to negotiations by the prime minister."
Meanwhile, Sinn Féin deputy leader Michelle O’Neill accused Secretary of State Karen Bradley of "staggering ignorance of the Good Friday Agreement which guarantees the rights of citizens, whether they identify as Irish, British or both".
It came after Ms Bradley appeared to suggest that Irish citizens living in the north could not vote in referendums, as was the case for British citizens living in the Republic.
"The British government cannot and will not be allowed to redefine Irish citizenship or rewrite the Good Friday Agreement," Ms O'Neill said.
"It also completely ignores the fact that thousands of Irish citizens voted in the European referendum in 2016. Is she now saying that they did so illegally?"
