Interesting! I used the QR prompt pay payment method and didn’t receive any email. However, I printed the invoice I found on the order history page. And I agree that AI might very well change the process in ten years!
I’m curious, did you staple the four corners of the photo onto DS84 and include another two photos with your package? Also, did you notice that the actual DS84 form is the last two pages of the 6-page PDF? The first four pages are instructions. Did you submit all six pages or just the last two? Thanks!
