Basically, the I-924 is an information-gathering tool for USCIS to assess the numbers and form statistics about regional centers. It could also theoretically provide USCIS with information (ammunition) to support a revocation of a regional center's designation, if it becomes clear that the regional center is not in compliance with the requirements. Since it is a fairly new form and process, no one really knows what the USCIS will do with this information.
Form I-924A will become available for public consumption on November 23, 2010. Regional Centers will need to file this compliance form beginning December 29, 2011.
As of this writing (Dec. 12, 2011), the jury is still out on this issue. The filing deadline for the very first I-924A mandatory filing is fast approaching and USCIS has posted Q&As on this but it will be akward this first time. It will then take many months before USCIS will publish any findings. Everybody involved is in the same boat. Congress wants information from USCIS and USCIS wants information from the Regional Centers. The stakeholders want information from USCIS and the Regional Center industry in general. The precise data that will be useful is still in a state of flux. Until a real reporting takes place and the data is suitably massaged, we won't know what is truly useful and attainable until it is tried. This will be more "trial and error" with plenty of errors. This is a natural process and will allow mistakes to be made from which to learn for the future progress of EB-5. Be patient, it's worth the wait.
