I was also approved on Monday! If I remember correctly, the only documents they asked for were my passport, birth certificate, marriage certificate, police certificates, one photo, and my wife's and joint sponsor's I-864's. Since I was DQ'ed Feb. 1st, I had only uploaded tax documents from 2021, and I hadn't uploaded anything at all since being DQ'ed. I had 2022 tax documents with me, but they never asked for them.
At the second window, he only asked fairly basic questions such as: How long have you been married? Is this the first and only marriage for both of you? Are you both living in Canada? How long has your wife been living in Canada? How many children do you have? Which countries have you travelled to in the last five years? Who is your joint sponsor? What does he do for a living? Why move to the US now? What is your occupation? He said the application all looked good, and he would approve it right away. He said processing time was 2 - 3 weeks and gave me a paper explaining how to track my package. I was only at that window maybe 10 minutes.
I waited in line outside about 50 minutes, got inside about 40 minutes after my appointment time, and was in the office about an hour and a half.
Now today I received an email stating that my passport had been shipped! I chose to have it shipped to our house since we are so far from their pick-up points. And now the tracking shows estimated delivery tomorrow.
