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?
IMM 5257:
Q3a - "Have you ever committed,
been arrested for, been charged with or convicted of any criminal offence in any country or territory?
Short answer, yes you should have disclosed it. Yes you did misrepresent. Despite not having been convicted, IRCC clearly wanted to know if you were charged with a crime.
In Q3b, it asks you to provide an explanation. You could have literally told IRCC what you just told us. It would have been fine. Hiding stuff is misrepresentation.
Your could withdraw the application, however, it could be the case the data from your old application is still retained in the system (maybe others would know). But by the time you withdraw, they may start processing it. It takes ages to even get a response for a withdrawal request.
But I don't think Canada and South Africa share data. That's not to say they couldn't, but Canada mainly shares data with its "five eyes" partners being USA, UK, Australia & NZ.
You may be lucky but you've definitely taken a gamble and if you were to apply for PR in Canada in future, this would jeopardize your application.
