Thanks for checking us out here in the Community, @dicctlb22.
The likely reason that you’re having trouble with changing the company address is that these are US based subscriptions. That said, we can only address your account inside US states. If you wish to use QBO outside US, I’d suggest canceling the subscription and sign up for another QuickBooks Online International.
You may subscribe to the international version of your home country by visiting this link: https://quickbooks.intuit.com/community/Getting-Started/International-versions/m-p/186273.
To transfer your data to your new subscription, use the Export to Excel feature. The following guide provides detailed instructions on how to transfer reports, lists, and non-posting transactions: Export reports, lists, and more.
Keep me posted if you have any other concerns or questions. I’ll be right here to help and make sure you're taken care of. Have a good one.
