As long as you can authenticate (and retaining EB5 counsel like our law firm will help!) each dollar used for the investment, you should be able to prepare an approvable petition. Your investment must be from your personal funds and placed at risk, so we would carefully review the loans you are taking for compliance. If you can review the location of the project and determine that it is in a Targeted Employment Area (or within a group of contiguous census tracts that qualifies), then you would only need to invest $500,000.
To be an EB-5 investor you only have to invest USD $500,000 if the new commercial enterprise and the business activity including job creation is located in a target employment area, known as a TEA. You as the investor may borrow funds and use these funds towards your personal investment requirement. But as the U.S. investor you will also have to show that the Lender obtained the funds from lawful sources and you as the borrower have the financial means to pay back the loan on a regular basis.
