My experience with the U.S. Embassy in Montreal was extremely pleasant. Everyone was welcoming, and I was greeted kindly at each step, from document checking to fingerprinting to the final interview. The consular officer was very understanding and professional, which made the whole process smooth and stress-free.
The most important thing is to make sure your current police clearance certificate (PCC) is up to date. In the worst-case scenario, if they need any document which you haven’t provided it, they’ll usually give you a 221(g) notice that clearly states what’s missing. Once you submit the required documents, they’ll move forward with issuing the visa.
That’s exactly what happened in my case. I was given a 221(g) due to one missing requirement. I submitted the updated document the next day, and within two days, my status changed from “Refused” to “Issued.”
