I was living abroad for 6 years and now back in India.?
Where were you living for last one month? Do you have any family or relatives? Did you establish your residency in country you lived abroad? If your relatives or family can allow you to used their address, you can apply forenewal.Other option is, if you can take risk, use address you established in other country, apply for renewal at nearest Indian embassy. It will be tough because you are in India now. You will have to coordinate with friend or family abroad. Fill out paperwork online, sign and send to your family/ friends abroad. Request them to mail it to embassy with all required documents. Once they get it, they can send passport to you by courier. Its risky, but you got to do what you need to do.
