Ireland want to help rugby crack the United States by hosting World Cup 2023.
Irish rugby chiefs will present their World Cup bid to the voting unions in London on Monday, with France and South Africa the other contenders.
Rugby World Cup will issue recommendations to the 39 voting bodies on October 31, before the final host decision is revealed on November 15.
European club leagues are already eyeing the potential for US franchises, while America almost launched a bid for the 2023 World Cup.
The Irish Rugby Football Union (IRFU) insist staging the 2023 tournament would push America ever closer to becoming serious contenders as future global competition hosts.
"We have put a really, really forceful proposal on the table to Rugby World Cup," said IRFU chief executive Philip Browne.
"If the rugby community is genuine about wanting to expand the sport, if they want to inspire people from other countries as potential hosts, then we believe we've made it easy for them to do that.
"What we'd see as a tripartite partnership has to be put in place, between Ireland 2023 if we win the bid, World Rugby and US Rugby.
"It's about what can we do to increase the footprint of rugby in North America."
The IRFU believe the 70 million-strong global Irish population can galvanise rugby's bid to break America.
Newcastle Falcons hosted Saracens in Philadelphia at the weekend in front of a crowd just topping 6000.
"I would hope so; the diaspora is not just about getting Irish Americans to come for Ireland to the World Cup," Browne said when asked if he would envisage Ireland hosting in 2023 paving the way for the US to stage a future World Cup.
"Ireland's Test match against New Zealand in November last year drew a crowd of 62,500 - that's the highest-ranking rugby event in the US.
"We worked very closely around the Chicago match with the promoters, who specifically targeted the Irish diaspora."
