hi @magrath ,
You may access your account anywhere by internet. But please keep in mind, QBO has many versions specific to certain country. When you are in Korea, QuickBooks by default will route your connection to the server of Global version, not Canadian one. You have to bookmark your current address on browser to log into your account for later use in abroad.
Another option, you may visit this link https://quickbooks.intuit.com/choose-country/ from anywhere and choose Canadian version.
Hope it helps.
