oohhh, now i understand. you can easily get another deposit slip at the ustraveldocs.com website. look under nonimmigrant visa. you should see the bank and payment options. in that section you'll see the appropriate link to get a new slip. when you received your approval notice, it should have mentioned that your case was being sent to NVC, and that NVC will send the case to where your fiancé will be interviewed, and after get notification that they sent it etc. I didn't get a letter i got an email. Covid has made them operate different than usual.
