I can't change the country in the App Store I don't know what the reason is possible to change it somehow?

What error do you get? Make sure you've completed all of the below:

• Zero your Apple Account balance. If you have only a small amount remaining, you can either buy an item more expensive than your balance and use a different payment method to pay the rest, or click and ask the iTunes Store staff to zero it for you.
• Cancel any subscriptions that block a country or region change, 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.
• Leave your Family Sharing group, if applicable.

Then, follow these instructions: Change your Apple Account country or region - Apple Support
