The statute requires a minimum investment amount and the Regional Center can't take its fees from there because your visa will be denied if they do. The Regional Center is spending money for the Regional Center application and all the required supporting documents. The RC has to hire lawyers, accountants, economists, business analysts, and a variety of consultants, subject matter experts, marketing experts, foreign agents and investigators, and even lobbyists. If the RC does a great job up front it can protect ALL its investors (including domestic investors and foreign investors who are NOT trying for a visa) and help their EB-5 alien investors have a smooth immigration process. Regional Centers are basically licensed by USCIS to provide investment projects geared to meet EB-5 requirements and advertise those projects. The RC must track information and report to USCIS and if it loses its focus or strays from its purpose, it may be terminated. Regional Centers are in business and nobody offers services for free. Ask for a breakdown of expenses at least in a general way. MOST RC's do not include the USCIS filing fees or your attorney's fees. The RC can't force you to use any particular immigration attorney. When it comes to the financial aspects seek wise counsel. This response is only on the immigration aspect.
All Regional Centers have additional costs over the required $500,000 to cover administrative costs, acquisition costs, and finders’ fees paid to agents who refer investors. These additional fees generally range from $35,000 - $60,000.
Most regional centers require the foreign investor to provide an administrative fee. The administrative fee usually ranges from $35,000-60,000.
So-called "administrative fees" are common and standard among EB-5 regional centers. To elaborate on the answer above, you are not getting ripped off. The regional center must place the entire amount of the investor's investment at risk and in the business. The investment cannot cover the costs involved in administrating your investment and entry into the program. As such, regional centers commonly tack on this fee to cover these expenses as well as the costs of marketing to investors, among other things.
