I had requested I-140 approval notice(I 797) through FOIA. But I got response from USCIS that my I-140 petition is currently with NVC - National Visa Center and I need to contact NVC to get the approval notice.
“As previously stated, the whole I-140 receipt file has been transferred to the National Visa Center (NVC). Which means we do not have access to any of the records and cannot provided you with the approval notice. You will need to contact the NVC”
When I contacted NVC they told me to contact USCIS to get the approval notice.
Can you help me with how I can proceed in this scenario?
