In same situation, I am the applicant and wife the petitioner. We both currently live in UK. We used her foreign income earned here in UK on the I-864 form and was just under the minimum requirement to which we were RFE’d for “evidence of income” instead. We submitted her last 6 months payslips and 2 weeks later, this weekend, were notified by NVC that we are now Documentarily Qualified. No further RFE or any note for use of a Joint Sponsor. Is this correct on their part or an error? Is it possible to be DQ’d like this?
