To transfer a warranty: The system must be registered to you with Dell, The system model must be sold in India, The system must have an extra-cost, on-site warranty (the basic 12 month warranty is return to depot and applies only in the country of purchase and the transfer will fail if this is what the system has). If those are met, the transfer should go through.  You'll need to call Dell to find out if there's a delay or denial (subject to the above conditions being met).  
Today I have applied for transfer of warranty to my another address in India. How do I check my status and when it would be transferred. I think it takes 15 days for international transfer. Is there any link where i can enter the request number and check status?
