Congratulations! Be wary of the SEC regulations S and D regarding broker/dealers and marketing to foreign markets. While it’s better from a control standpoint to keep it all in-house, working with an established, reputable firm in China will have the benefits of their established network and brand. Of course, you would definitely want qualified EB-5 counsel in the U.S. to represent your regional center and projects and review any work product of a Chinese broker (or to represent the investors outright).
First retain an experienced EB-5 attorney who will be able to guide you in developing a relationship with a credible USCIS and SEC compliant brokers.
