Husband got denied for I-485 due to insufficient evidence for a joint sponsor. When they sent the RFE it asked for evidence for a joint sponsor however we did not list one on the I-485 so we sent in more info for the petitioning sponsor, which is me/his wife, and we got denied. In the denial letter is does says we can file a I-290B and submit correct evidence. Should we file the I-290B or completely refile the I-485 with all new/correct evidence?
