Happy to share that I had the interview this morning and the officer said I will be approved. Hoping to receive the passports soon.
Overall very smooth process, consulate staff were courteous, officer was great! Same questions that everyone has shared earlier: Workplace, Role, Company etc and some general questions about education and previous trips to the US. Documents request was nothing outside of the usual, all the standard docs listed on the Montreal specific page: Birth certificate, Police Certificate, Marriage/Divorce etc.
Thanks all in the forum for keeping the convo going and the last 28 months since DQ (June 2020) were definitely not easy but became easier and more predictable based on experiences shared here. Wish you all the best, thanks!
