I applied for a visitors visa and failed to mention I had been refused a South African visa before because I appealed the refusal and the visa was eventually reinstated. I also was a victim of visa scam in South Africa and was arrested for it but after proving my innocence , the state withdrew all charges. I selected No to the question asking if ever been charged and I’m scared that I might have misrepresented. My Canada visitor visa application status show background check in progress and they’ve not started checking for eligibility. What can I do to avoid a ban?
