In answer to your question the answer is yes and no. You pose questions which require the legal advise of an experienced EB-5 securities attorney. You will have to understand the parameters of general solicitation, Reg D and Reg S exemptions.
As an attorney that practices US Immigration law exclusively, I do know that most, if not all, Regional Centers require investors to complete accredited investor questionnaires to comply with SEC Regulations, which include net worth requirements. Retaining qualified EB5 counsel, like the attorneys at our law firm, can help investors and project principals coordinate with other professionals to navigate the issues that may arise, and develop approvable strategies.
