How do I get an Indian passport renewed in the US?
No need to go to the Indian consulate. People living in the U.S know how arduous it is to travel to the nearest Indian consulate. Here in the U.S, you have to do it online (through the CKGS) only "Indian Passport Application Center". CKGS (Cox&King Global Services) is the only authorized service provider for all the services required from the Indian consulate in the U.S. Regarding the change of address, it is not a big deal. You have to submit proof for your new address, a lease deed or Utility Bill or state ID with the new address. All the best.
