The Football Association of Ireland is set to join England, Scotland, Wales and Northern Ireland in launching a joint bid to host the 2030 World Cup.
The four nations had already announced plans to assess a bid and now the Football Association of Ireland says it will join a feasibility study "following recent positive discussions amongst all parties."
Dublin's Aviva Stadium will be used at Euro 2020 with three group matches and a last-16 tie being staged at the venue.
England, which last hosted the World Cup in 1966, failed with bids for the tournament in 2006 and 2018.
Argentina, Paraguay and Uruguay have already started collectively campaigning to host the 2030 World Cup while Tunisia have shown interest in backing a north African bid alongside Algeria and Morocco.
