Thanks a lot! Could you perhaps explain this a bit more in detail:

"The investment has to be made by the people applying for the visa."

Let's say that we're a 2 year old company in a treaty country (EU) with ~$400k in the bank, founders have ~50% of the company. Not having a US company yet. Would this situation require some tweaks before applying for a E2 visa?

Also:

"Your employees can also move to the US under this visa."

Under which circumstances can the (EU) employees transfer? The same time frame as the E2 holder? Would it be sufficient for only one of the two founders to get the E2 visa and let the other move as an employee?
