Have you considered applying for EB-5 investor visa as an option (apparently the date is current for India)? Are there further restrictions other than the chance of losing the investment?
It will take 2 years to get a temporary Green Card. Even after that it take 2+ years to get Permanent Green Card, and it depends on a third party creating and maintaining jobs. So starting now doesn't help in the immediate term :( And too much uncertainty for longer term.
