I got a 2 messages from NVC.
the first said that All required documents have been received and approved. the second one said
"The police certificate required for Japan is not needed in order for the interview to be scheduled. However, the police certificate must be obtained and submitted before the visa interview. For information regarding an acceptable police certificate, please use our Document Finder at https://nvc.state.gov/find"
I went to the documents section and in the response note is says
"The police certificate required for Japan is..."
My wife and I went to the Prefecture police depart where they took her fingerprints and we went back 2 weeks later to get the Police certificate.
The police certificate is in a blue envelope from the prefecture we live in with my wife's name and
"To: The Authorities Concerned, United States of America (Content: Certificate of Criminal Record )
the back has stamps on the edges where the envelope opens.
when uploading I copy and pasted the special seal/format section from the state.gove site in the comments.
Did i get the wrong document or did the person reviewing not know about Japanese police certificates?
