Thank you for reaching out, Muhammad.
In QuickBooks Online (QBO), the region of your account is determined by the specific regional website from which you purchased your subscription. The country associated with your account is fixed during the creation and cannot be changed.
If you have already subscribed to the US version, we recommend canceling it to avoid additional charges. Then, you can create a new QBO account and choose the country you want to subscribe.
You can also use the Multicurrency feature to record foreign currency transactions.
After signing into your new QuickBooks account, learn how to set up your company settings and explore the dashboard by reading this article: Get Started with QuickBooks Online.
Please let us know if you have any further concerns about your subscription. The Community is always here to help.
