I'd prefer a 3v3 as well.
In fact I could play for Ireland cause I do possess an Irish PPS. Thats the Irish personal number.
Gry however studies in Belgium and doesn't have a Belgian personal number I think? Yet again, Gry lives in Belgium for a long time already and speaks Dutch perfectly. If anything he should have had the possibility for a Belgian personal number before I should have had in Ireland. Still, I worked in Ireland and he studies, major difference.

Summary? skip this post its boring
