Changing your account service and shipping address to a different country than the country used upon sign up is not supported.
You can permanently transfer your Starlink onto a new account to any country Starlink is actively serving (starlink.com/map). Transferring your Starlink will cancel your current service and remove the corresponding Starlink hardware from your account. See transfer requirements here.
After you have completed the Starlink transfer process, you can create your new account with the new country's service and shipping address. Creating a new account requires the use of a new email address. Visit starlink.com/activate to activate your Starlink.
