As an experienced EB5 attorney I would convey that the larger number of successful EB-5 projects are new commercial enterprises in which the new projects are requiring and showing new job creation.
From an immigration standpoint, investing in a new business is probably more straight forward, as you just count jobs created as a result of the investment, and do not have to consider current and past employment. From an investment standpoint, you will have to review the investment with an accountant, financial planner, business attorney, etc. Our law firm often refers our investor clients to other professionals experienced in these matters, and review any immigration consequences of their plans.
