what age do you leave orphanage
It's a grey area as the child can live on their own from the age of 16 but generally they are cared for until they are 18. However there is a duty of care until they are 21 if they need it and I do know of someone who was at university so she did get support until she was 21.

In the UK fostered children either live in a care home with staff taking care of them or they live with foster parents.
