My husband faced a similar situation. His visa was granted immediately, but we had to wait for over four weeks for his passport without any additional requests. Surprisingly, it then went into administrative processing, despite no further documents or questions being requested, only to be denied later on the grounds that we lacked strong ties to Canada. This situation is utterly absurd given that I am a Canadian citizen, he holds permanent residency, and we both have stable full-time jobs and own a house in Canada. I strongly advise you to proactively reach out and provide documents for financial proof and evidence of your strong ties to Canada. It appears that even though they verify financial information and employment during the interview, these factors are somehow overlooked during processing, leading to a baffling outcome without any document requests for review. The US visa processing system seems to be highly flawed. Unfortunately, there are no adequate phone numbers or email addresses for inquiries. I wish you the best of luck and hope you can find a way to contact them or submit additional documents for your visa application. All the best!
