Thank you for your message. You can get the warranty & ownership transferred from Canada to the USA without upgrading to a Premium warranty. An on-site warranty is eligible for the transfer in this case. The service options available in both these regions are the same.   Only in case you are moving to a different country (ex- Canada to Australia), you will need a Premium onsite warranty as the service options may not be the same.   For example, US & Canada have depot service, but this is not available in many other countries.   If you need assistance with the ownership transfer after the warranty upgrade, feel free to reach out to me, I will be glad to assist you.    
Hey, I am looking to renew my warranty for my XPS but I may move to the US next year so I have asked if the warranty would be transferable from Canada to the US. The rep first told me it would be fine and then told me that I would actually need to add "Premium support" on top of the "Onsite/In-Home Service After Remote Diagnosis" I am looking to purchase. Can you confirm?  Thanks!
Canada to US Warranty
