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 etcI 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!
