Can I get Warranty services in india for an ipad imported from the USA ?? Also, am I eligible to buy apple care plus for this ipad ?

Apple provides an international one-year limited warranty for products purchased in some regions. Warranty service is limited to the available service level in the country where the warranty claim is made.

AppleCare+ is only valid in the country of purchase.

Generally, you should aim to purchase a device in the country within which you intend to spend most time - as this often simplifies the warranty position should you ever need to call upon it.
