Hello Vladislav_sodzerovih, we cannot help you with your request from here, as you are writing in a forum where users are, to the best of their knowledge and within their means, helpful with questions about Apple devices or software. We are not Apple Support and therefore cannot access your Apple Account.
You can use your remaining credit either for a purchase or for an subscription. If this is not sufficient for that, this will be used first and the remaining balance will be settled from your registered payment method. This of course only works if the payment method you have registered is active and can be used. If you do not wish to do this, contact Apple Support.
To be able to change the country or region for your Apple Account, there are further points to note that you can view here. Change your Apple Account country or regionApple SupportOfficial Apple Support › en-us
Before you update your Apple Account location:
* Spend any remaining Apple Account balance: You can spend your remaining balance on the App Store, other Apple services, or, in some countries and regions, Apple products and accessories. If you’re not sure if you have a balance, check your Apple Account balance.
* Clear a low Apple Account balance: If your balance is less than the cost of a single item in the App Store or other Apple services, learn how to clear your balance.
* Cancel subscriptions that block a country or region change: Cancel any subscriptions that block a country or region change, then wait until the end of the subscription period.
* Wait for pending activity to clear: Wait for any memberships, pre-orders, movie rentals, or Season Passes to complete. You can cancel a pre-order. Also wait for any pending refunds from Apple to process.
* Check your Family Sharing status: If you’re a part of a Family Sharing group, you might not be able to change your country or region. Learn how to leave a Family Sharing group.
* Have a valid payment method ready: You might need to enter a valid payment method for your new country or region. If you don’t want to enter a payment method, wait until you're physically in your new country or region. Then create a new Apple Account.
* Redownload your content: Some types of content might not be available in your new country or region. Redownload your apps, music, movies, TV shows, and books on any devices that you might use to play or read them in the future.
