A vote for the Irish abroad in presidential elections is to be discussed by the Constitutional Convention in Malahide this weekend.
The meeting will include representatives from Irish groups in Australia, the US, and Europe.
Over 100 countries allow citizens living overseas to vote in elections.
Ireland currently has no such provision.
The convention will vote tomorrow on whether or not to recommend its insertion into the constitution.
If it votes in favour, the proposal will then go forward to the Government for consideration.
A referendum to amend the Constitution would also be needed to enable emigrant voting.
The Constitutional Convention is a 100-strong body of citizens and parliamentarians chaired by Tom Arnold.
It was set up in 2012 to examine and recommend various changes to the Constitution.
