I would first retain the services of an EB-5 experienced Attorney who also has expertise in immigration taters such as waivers and obtaining permanent residency status. You can convert an E-2 status into an EB-5 status if you comply with EB-5 regulations and policies. If the investment requirement is $1 million or $500,000.00 the investment has to be derived from personal funds and not retained earrings being reinvest end the business. Waivers of grounds of inadmissibility may allow non- immigrant visa entry such as the E-2 visa but the same waivers may not allow the approval of US permanent residency. This is why you will need to consult with an experienced immigration attorney.
