The residency requirement has officially increased from three years to five, meaning players who move countries as adults must now wait significantly longer before becoming eligible to represent their adopted nation.
In simple terms? The fast track is gone.
For Ireland, the impact has been significant.
Join the RUCK’s WhatsApp community here and get the latest news sent straight to your messages. Jamison Gibson-Park, Bundee Aki, James Lowe and Mack Hansen all relocated to Ireland as professional signings. Under the old three-year rule, they became eligible quickly and went on to play pivotal roles in green.
Under the new five-year threshold? At best their Test debuts would have been delayed. At worst, some may never have pulled on the jersey at all.
That represents a huge slice of Ireland’s foreign-born contingent in recent seasons — players who have been central to Six Nations titles and World Cup campaigns.
Scotland would also have felt the squeeze.
Pierre Schoeman and Duhan van der Merwe qualified via residency after moving from South Africa. Both became key figures in Edinburgh and then on the international stage — but both would have had to wait an additional two years under the current rules.
By contrast, Sione Tuipulotu qualifies through ancestry — his grandmother was born in Scotland — meaning the residency extension would not have applied.
What does it mean?
The days of rapid international reinforcements appear numbered. Nations that have benefitted from experienced imports may now need to double down on academy production and domestic pathways.
For Ireland and Scotland, it could mean fewer ready-made upgrades from abroad — and more pressure to develop from within.
World Rugby may not have trumpeted the change loudly, but its impact could quietly reshape the competitive balance for the next decade.
Poll:
Every Nations Championship squad ranked by foreign-born players – from least to most
Using information and research from Americas Rugby News, we have ranked all 12 Nations Championship squads from the lowest percentage of foreign-born players to the highest.
It is important to note that foreign-born does not necessarily mean a player was developed overseas. Several players on this list moved countries as children and came through the rugby system of the nation they now represent.
12. Argentina – 0%
Foreign-born players: 0/35
Argentina are the only team in the inaugural Nations Championship with a squad made up entirely of players born and raised in the country.
Felipe Contepomi’s squad also highlights the continued growth of rugby outside its traditional Buenos Aires stronghold.
At the 2007 Rugby World Cup, 27 of Argentina’s 31 players came from Buenos Aires province. In the current squad, that figure has fallen dramatically, with Córdoba and Tucumán now producing a growing number of internationals.
Foreign-born players: None
11. South Africa – 2.17%

Rassie Erasmus has selected just one player born outside South Africa.
