Hi there, LRATX.
You can access the QuickBooks Online (QBO) for UK company file even if you're currently staying in United States. Just make sure you're using the correct link when logging in to your account.
Here's the link for UK and US login page.
About the access limitations, can you provide a screenshot of the message? Are you getting this message when trying to access your company file?
If so, please click the Reply button below and share a screenshot. It'll help us check the main reason why you're unable to access your account..
