Apple Store

Hi  mushtak112,

The following steps address what you're describing specifically, and should provide a solution:

"If you can't change your country or region

• If you can't change your country or region, make sure that you canceled your subscriptions and spent your store credit. Complete these steps before you try to change your country or region.
• 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.
• If you still can't change your country or region, or you have less store credit than the cost of a single item, contact Apple Support."

You can find these steps along with other information that may be helpful, here: Change your Apple ID country or region - Apple Support

If you have followed the steps correctly and you still have the issue, let us know if you get any specific alerts or error messages when trying, as those may help us determine what might be causing the issue.

If you still have questions, reach out to Apple Support directly, as this may require closer guidance: Get Support

Cheers!
