My husbands visa application went in on 21 Sept 2018...12 months later we receive a request to send more info concerning police check. If your UK certificate says No live trace you need to call police and get full details of what they have on you and write everything down on the appropriate form. These minor no charge offences go back 45 years in my husbands case. It took Canadian government almost 12 months to let us know we needed to do this. In fact we have paid an immigration specialist and they did not inform us that we need this info. We sent info almost two months ago so we are heading into 14 months of waiting for a letter of confirmation. We have an Ontario marriage certificate and wife is Canadian sponsor. Just saying.
