when I did it if I recall took 4 to 5 weeks and had the NVC letter emailed to me but again that was few months ago. Now I did email NVC using the inquiry form on the 4th week and next day they emailed me the number and I recall few days to a week later I got the letter in the email

@R B thank u, imma try to send the inquiry form to get the case number

I approved before 10 days and still don’t receive welcome letter from NVC

@Y S they said I should get the letter by Dec 15

I approved by Oct 31 nothing yet from NVC
