There are Nurses who studying NVQ here, They said they applied thru Affinity and paid lots of money then you can work as carer
Why not try in New Zealand? You will also spend money but your visa will be working visa and work as Carer if you are not yet an RN.
That was the same advise I told to my 2 nieces but they are both RN and need to take CAP and pass their IELTS. After CAP, they can work in a hospital.
It's unlikely to come here and take NVQ-Caregiving course and work 20 hrs limit as Carer
Goodluck!
