Somebody knows if it's posible to register a .in domain if I live out of India?

Regards

As far as I know your business should be located in India.

Unlimited registrations are available in the following zones. Registration is available freely to all parties worldwide, and there are no nexus or other qualifications:

http://www.registry.in/policies/

i think its freely available to anyone, as i have seen few people from uk registering .in domains few months back when there was a .in sale in my reseller club domain register

No restriction on .in registrations.

Yo do not need to have business in India. I have googled for the .in domain name registration. Most of US located web hosting companies offer .in registration. I have seen it on Hqhost.net web site
They might be Directi resellers but if they offer that it must be legal and available for registration for non India residents.

I think yes you can buy domain name if you are outside the INDIA

Is there any such rule? I don't think so. I know an Indian guy who has registered .us

no such restrictions for.in domains

It should have been available to the place to which it belongs. But every indian extension like .co.in, .in, .ind.in etc. are available worldwide!
Thats why you can easily register them at domainsite, godaddy etc.
