Hey there. So what was the outcome of your application? I have a similar situation and was checking this forum. Wanted to know if things worked out and if cic asked you any explanation?
I completely agree with you that it was a mistake, but I did some research too and I found that for misrepresentation the mistake has to be a material fact affecting the visa decision which I doubt for my tourist visitor visa would matter between divorced and single.
And I agree that the letter might help but do u think I should send the letter along with the application or I should wait for their reply first ?
