I've been waiting a total of 85 days through contacting USCIS and NVC with enquiry and I contacted a week ago the congressman but I don't have any news yet. Even though the i797 was sent to NVC, in the portal of uscis says still only approved. NVC didn't receive the case yet. They congressman've made a inquiry and we are waiting. My i130 petition was sent through mail, maybe is causing a delay. Before the 90 days came, I want have some informations for what to do next.
