My fiance I-129F has been approved. During his interview he was asked for his passport and the name on the passport did not match the name on the petition. He has been given a 221(g) and in it states he needs to bring proof of the family name used that the petition his approved by. He found historical documents that states his family name and we hired a lawyer to submit his paperwork that proves his identity. Should we change his passport and his national ID card to the name that the petition has been approved under or should we wait and see what direction the US Embassy will give us as far as his name change after we submit the evidence???? Does the name on the approved petition need to match the name on the passport in order to get the visa issued? Will US Embassy issue his visa under the name that is on his passport and not care about the name that his petition has been approved by? Thank you
