Here is my case. I filed my I140 and I485 last september in EB1b catergory to VCS. I'm the primary applicant with my wife and my son as dependent. Both I140 and I485 were approved by vsc this year. My wife and I received the green card already. Unfortunately my son's petition for I485 was denied recently for the reason of that primary applicant's case was denied or withdrawed. I figured that my son's case was separated from us during the process because RFE for my son fingerprint was late for six months comparing to mine. Xiaobaitu or other experts, please tell me what I should do to reopen the case, and how can I initiate the appeal process, and which kind of evidence I need to present to uscis that they denied by mistake.
Btw, the denial letter mentioned that the regulation do not provide for an appeal from this decision. In the current situation, does my son be out of status in any term?
thank you all in advance
