Update on my case -
I just got an email to schedule my appointment. Earliest date that I got was Jan 7th. The email said the following.
"The U.S. Consulate in Toronto has received your visa application. However, your application does not qualify for the interview waiver program and you require a personal interview. Your passport will be returned to you through Canada post. Please proceed to schedule an appointment after you have received your passport."
I am a Canadian PR, my last stamping was through Dropbox in Toronto. The only thing that has changed for me is the employer. I am assuming that disqualifies for Dropbox now.
