Change country apple store

You need to ensure the following are done-

1. Spend any store credit remaining on your Apple ID. You must also wait for any pending store credit refunds to process before you can change your country or region. 
2. Cancel any subscriptions, including Apple Music, and wait until the end of the subscription period to change your country or region. You'll also have to wait for any memberships, pre-orders, iTunes movie rentals, or Season Passes to complete.
3. Have a payment method for your new country or region on hand.
