I want to transfer my Apple Store account to a Saudi account, and I want to zero the account

I understand that you may want to change the country and for that, your credit balance must stand at Zero.

The options available to you are...

1. Add more funds and buy something useful else
2. Learn what to do if your remaining store credit is less than the cost of a single item.

Not registering in Apple ID and when I enter, they give me that it does not accept a free account and I must complete the process in iTunes, what is the solution?
