QBO country

We are a UK company (registred in Companies House) but we will not be using Quickbooks to file our VAT. A lot of our business is doe in the US and Europe and QBO does not do well with multiple VAT rates and mixing VAT with sales taxes. We understand that we would use our QBO only as a bookkeeping tool. 

Can we sign up for QBO in the US? We would like to be able to change the language within quickbooks and QBO UK does not offer this. 

If so, do we need to cancel our current account and start a new one?
