Thanks for your advice. We've heard similar stories before (about how to find an US resident as a co-founder to do all the "work"). Working on our OPT may not be an option for now though, as we are not near to graduation...
But what if we don't found a company at all, just receiving app/ads income from our app to your personal accounts? any F1 students got problems with that before?
The question is not if people got in problem for that, the question is, is it illegal. And no, as far as I know, it is not legal. Still I know people who do it and it really depends on if you want to stay in the country and try to become a resident etc. If you do, it could be too risky.
How about starting a company back in your home-country?
Ya, starting up a company in our home-country is another option we are thinking, but we are targeting the US market, not sure how complicated the international business thing could get...
