My son attended his immigrant visa interview this week and was denied about the information on his school certificate. His passport information has my last name added to his names but his school certificate does not. They stated that further consideration will be given to my visa after I have obtain and present the documents required. They did not give any document submitted to the embassy to back him except his passport. They concluded that if I fail to take action required within one year following visa denial under section 221(g) of immigration and nationality act, section 233(g) of the act requires that my application will be cancelled. I am in the process of swearing affidavit to get the information on the passport rectified. What is the process of submitting the requested documents to the embassy. How soon, and how can I get another visa interview scheduled? Do I have to submit the documents to the embassy or I have to send them to uscis or nvc? Your responses are highly appreciated. Thank you.
