US marketed iPad Pro warranty in India
Apple products have International warranties but only in the countries where it has, it's own Stores. In India, there are no Apple-owned stores yet. They are Resellers authorized by Apple but they won't service your device because you won't possibly be taking it to Apple-owned stores. I hope this suffices your query.
