we are a family and my wife was selected for DV2016. After submitting all the necessary documents, the interviewer kept the original school documents by saying that she would check them. she requested us to provide public charge concern which was later sent by DHL. But exactly after 2 months of the interview we received an email saying visa refusal under section 212(a)(5)(A) INA. After asking for clarification, we were informed that the high school documents of my wife were not authentic and advised to provide verifiable documents in future. we know all our documents are genuine but the embassy could not verify them because of its relationship with my country. we are heart broken knowing that we are genuine applicants. what could be done? do you think appealing or legal procedure works? thank you for your advises.
