I believe that an expired certificate is not really an issue for IRCC - so take heart, perhaps it's human error on the part of the IRCC agent... Hope you can solve it soon - all the best!Everything is ok. The name, color scan, format etc I submitted two certificates, one from England and one from Iran. The other one was accepted but the one from Iran is the problem. The only problem that I think about could be the date. The letter was issued in January and it was valid for one month" (all police certificates are only valid for 1 month - government rule). I submitted in that 1 month period but now the letter is not valid!
