Hi Shimsha,
CARA has its own requirements for adopting within India. I believe you have to establish one year residency to begin adoption in India. You can check CARA's site:
Central Adoption Resources Agency for more exact guidelines.
For the US, the child needs to be in your custody for two years before being eligible to apply for entry to US. See
U.S. Citizens Abroad
So, this might be an option for you if you return to India for about three plus years (the plus being the adoption process time in India).
Unfortunately, there doesn't seem to be any quick way around adoption from India. Now that the Hague treaty has been signed by the US (April 2008), there are even more restrictions and fewer options available in Indian adoptions.
Regards,
