I posted this on the living overseas board but I don't think it's particularly active so reposting here for traffic.
My parents in law have just come back from visiting their daughter, her husband and kids in Melbourne. They have told us that due to the health benefits of living in a warmer climate they want to move over there permanently and are seriously looking into making it happen.
We are very close to them and my kids absolutely adore them. Whenever they leave to visit, usually for a few months at a time, my kids are incredibly upset and miss them terribly. If PIL move away permanently they will be absolutely devastated.
They are in their late 60s and financially comfortable. They suffer from some health conditions. How realistic is it that they would be granted permanent residency?
