Here are a few points I have. 1. Understand the business of Startups: Startups are usually ideas to 'fill up a gap'. With Logic, you are more likely to find gaps in a less matured market.
2. Why Emerging markets, are better than Matured markets: It is hard to believe that 1.2 billion people will not contribute to be one of the best economies of the world. It's hard to believe that there wont be enough business opportunities in India. (Same goes for China, which is already on top, and other emerging markets like Africa etc.)
3. Who will be winners of future? I would imagine people who are slogging to get the emerging markets better will be at best position in future.
3. If you think there is some kind of lack of opportunity in India. Well create one. If you think there are ways you think things should happen, well you should work to work those things out.
On VISA Issue: With Startup VISA coming, it might make a few things easier, but only time will tell the right story.
