Well, it depends. I know that your child education is in the first place. But you have to take in consideration his life here where he lives now. His friends, his company in school, various factors should be considered. Also, you should talk to your kid too, to see if he wants to move in the first place. What if not? Would you still move against his will? It could cause only but problems in the long run. I think it is a great decision to be taken by you alone, you should talk to him and see if that solution is even possible.
