> Can you travel in and out of the US as often as you want while on this visa?
Yes
> What would be the standard criteria for having the visa renewal approved? Would they need to see revenue growth? Would a stable stream of revenue be sufficient?
You provide them with a forecast and the idea is to meet the goals or show some progress on the project I guess (employees, paying taxes etc) - can tell you more in 2yrs :)
> Can you start other companies while on this visa?
Sure but the visa is connected to the company you made the investment in.
> Can you invest in other companies on this visa?
Think so, why not. If you invest in US companies as an individual the nationality does not really matter (e.g. we're raising under a convertible note from non-US investors).
> If you have existing employees from non-treaty countries, can they come?
Not sure but I guess you have to look for alternatives like H-1B.
> While on the visa, can you hire new employees from your home country and get them visas?
Not 100% sure but it should work; as far as I have heard the visa can be extended to other people employed in the company.
In this case you could do a so-called flip bringing your assets from the EU to the US (contributing cash and assets).
A drawback is everything depends on the main E2 visa holders - as long as this person holds the visa others can follow; if this person does not hold the visa any more, all attached immigration permits are gone as well (e.g. if the company goes out of business you can't stay in the US and look for a job).
