The best approach is to retain the services of an experienced EB-5 attorney who may advise you on the EB-5 projects that have had or will have a successful EB-5 history.
While there are databases available for active Regional Centers, you would have to contact each directly to learn of their actual projects. With the assistance and representation of experienced EB-5 counsel, however, you can be introduced to regional centers with successful immigration histories. Please also remember that the EB-5 project does not need to be in the same state in which you will live. You could invest in a project in Ohio, Florida, or any other state in the U.S.
