Let me share some information about changing home currency and the country in QuickBooks, Nour.
Please know that we can't change your home currency if you enabled multicurrency feature in QuickBooks Online (QBO).
Once you sign up for a QuickBooks Online (QBO) subscription under a specific country, you're unable to switch to a different region, as this may affect previously entered transactions and lead to discrepancies in your books. However, you can create a new account to select the desired country. You can go to this link to sign up for a new subscription and select a new country:

You can always inform us in the comment section for additional questions about changing country's account and your home currency or other related concerns in QBO. We're always here to help you.
