I'm helping a friend (naturalized US citizen) bring his fiancee from Pakistan on a K1 visa. His NOA was 3/18 and NVC didn't get his file (which we found out after 2 inquiries, first at 30 days and then at 60 days). It took a two-week search after the second inquiry and then on 6/7 he was notified that NVC had received the case. Today, he got the NVC letter with the Case Number (yay!!!). However, there is no NVC invoice number on this letter, so he is unable to take next steps.
Can anyone inform us if the NVC letter with the case number should already have had the invoice number? Or is that assigned by the Embassy once they receive the petition? We submitted inquiry #3 to NVC about it but any information would be helpful.
Thank you!!
Susan
