Hello @soha
Regrettably, you would not be able to use a machine purchased in India, in the States. The electrical voltage 110/120V would be too low for your product, and using an adaptor or converter can cause damage to your machine.
While your machine does carry a 2-year limited manufacture warranty, this warranty is against manufacture defects. It does not cover wear and tear, accidental damage, lack of maintenance or incompatibilities due to relocating.
Per Dyson US policy, we would not be able to honor an exchange, as it is not a manufacture defect. As you are relocating to the US permanently, we would recommend purchasing a US model. We offer both new and refurbished machines on Dyson.com.
We do have a related Community article that helps to answer this questions.

If you wished to discuss this further, please contact the team in America. Their contact details can be found on our ‘Support’ page.
Thanks,
Stuart
