I would like to know the advantages and disadvantages of starting a company in India in contrast to the United States.
As far as I am concerned, I have seen companies (not all) set up in the United States seem to be well established both in terms of profits and as a brand than those in India.
The points that I would like to ask in this question are:
Kindly, reply me.
Its not the geography, its the legal framework.
In the US there are many (50+) different jurisdictions, and there are significant differences between incorporating in California, and in Delaware, for example. So its not just India vs US, its US vs US as well.
Most of the time, you would want to do what's convenient to your business operation. So if you're located in India, operating in India, and want to appeal to Indian customers - it would not make much sense to register your company in the US.
If you want to appeal to US customers, they might find it intimidating you having Indian registration, since it means, among other things, that they'd have to go to India to sue you. If you have presence in the US, you'll have to register in the US in any case (either as a domestic corporation or a foreign corporation doing business in the US).
Silicon valley start-ups get recognition because of connections, not because of the blue skies of Northern California.
