I think you can. I have been waiting since August and raised a webform as soon as I saw the processing time.the processing time of CEC via EE inland officially changed to 5 months. Does this mean everyone wanting from Oct AOR for CEC can raise the issue in webforms, since it exceeded their normal processing times.
