Hello support! I have no balance in my Apple ID and I have canceled all my subscription yet the system wouldn’t let me change my region, can someone help me ?

Have you fulfilled all of these requirements in order to change your country and region?

• Spend any balance remaining on your Apple ID. If you're not sure whether you have a balance, check your Apple Account balance.
• Cancel your subscriptions and wait until the end of the subscription period. 
• Wait for any memberships, pre-orders, movie rentals, or Season Passes to complete, and wait for any pending store credit refunds to process. You can cancel a pre-order.
• Make sure that you have a payment method for your new country or region. See what payment methods you can use.
• Redownload your apps, music, movies, TV shows, and books on any devices that you might use to play or read them in the future. Some types of content might not be available in your new country or region. Learn what types of content and services are available in your new country or region.

Have all your subscriptions expired after being cancelled?

Cancelling them is not enough, they must completely end before you can change countries.
