Tagging so I can read about EB5 and come back later. But at first glance, and with my limited experience in tech as a founder & VP, 500k sounds far too little for 10 FTE for 2 years.
Edit -- I'm sure you've looked into it more than I have, but according to the link below, I'm seeing minimum amount for TEA of 900k if filed after Nov 2019?
