Dilwalla,
You don't need to give a reason to NWD as to why you want your packet 3 to be mailed to India. Also remember that a large number of people go for green card directly without having been to the US unlike people who go on F1/H1B and then file for green card. In short it is fine to receive a package in India. However, as always check with your lawyer before taking any step.
