For those of you with a parent in long distance from you; specifically in a different country from where you reside and work. How does that work? Does the foreign country have a decree that the appointed person have to be a resident of said country where patient is?

I'm trying to navigate that with my mother who is based in Ireland and was just admitted to the hospital recently. I only just found out from my uncle who was listed as her next of kin, because he is physically closest as far family is, that mum still haven't gotten anyone appointed to be her POA, which is disappointing. Last i saw her in October at her previous hospital stay, she said she'd look into it. But honestly what recourse does a family member who is overseas have when a parent haven't set anyone up to be POA?
