You could always look at an E2 visa if you don't want to invest $800,000 in an EB-5 project; however, investment amounts vary from $150-400,000. The range is based on what USCIS would consider a "significant investment" based on your country of citizenship. E2s don't lead to a green card or US citizenship, but you may find a USC/PR spouse or another path while saving some capital.
Either E2 or EB-5 will have significant fees associated with them. Typical EB5 "administration/syndication" fees will run $80,000. You may be able to reduce this by going to the EB-5 Project directly and negotiating. Most of the time, 90% of that fee is used to pay a foreign agent(aka finder) for bringing the investor
It wasn't explicitly shut down, the regional center program failed to be reauthorized by Congress. Investors always could make a direct EB-5 investment, but there are fewer of those around.
Do you have any tips for finding a good regional center? And what is the deal with all these agents/finders that want to charge $80,000 for an "Administration Fee"?
