Hey there, thank you for your question. While international warranty services cannot be purchased since it is tied to the model of device and the Yoga 7i is not eligible, but by visiting the webpage tied to the following link: (https://pcsupport.lenovo.com/us/en/iwslookup#/ideapad), users can view local Lenovo Support contact and service options for the supported countries. Upon purchasing, you can look up your exact options by entering the product serial number in the search box at the previously listed link, selecting “International Warranty Services” within “Warranty & Repair”. Full disclosure, there can be some limitations with repairs abroad as US components and onsite repair may not be available in another country. Hope this helps!
