The last time I looked into it, it was based on a point system. By the age of 45 your out of their point system and more of a burden vs a contributing part of society. They want folks that will work to pay into the system before they retire and take from it... At 45 your not going to be a big payer into the system.. Im not sure but I still think it was after 9-11 that I was looking at moving there. There is way, way more restrictions now than when I was looking to move there.
