The filing of the I-829 comes with its own unique challenges, different from those faced in the I-526 petition. While remaining with the original attorney does indeed afford you with consistency, retaining an experienced and qualified EB5 attorney like the attorney at our law firm can help you prepare and file an approvable package with USCIS. A new attorney would correspond with the Regional Center to obtain all the necessary documentation for the filing, and prepare the forms and other supporting documentation.
It depends on your level of satisfaction as you go through the process. Did the initial attorney who filed the I-526 make mistakes along the way? Did you get hit with a huge RFE? Did you initially get denied and thus were forced to file an appeal and worse, a Motion after the Appeal was denied, or even worse than that, did you have to file in U.S. District Court or a Court of Appeals? If you answered YES to any of those (even just the first) then you might want to shop around (quickly).
You can retain a different Attorney to assist and represent you with the filing of the I-829. In fact our law firm has represented many investors in the preparation and filing of the I-829 petitions.
