I Have A 16 Year Old And I Am Getting Married I Am His Grandmother His Mothers Mother, And He Wants To Come And Live With Us When We Get Married May 3 What Does He Need To Do, Or What Can I Do?

First it is not a good idea to post a question as a answer to someone else's question, I have moved this to a post of its own.

Grandparents do not work like parents, unless the mother and father does not want them, or unless their parents are a danger to them, or unless the parents will agree just to let you have the child, there is not a lot you can do.
