I'm not sure about ICAS but I recently sent my documents to WES to get my ECA. I applied on the site on June 3rd, they confirmed receipt of my documents on June 12, I just checked it and now it says "Evaluation report being prepared for delivery". I'm guessing they are almost done. I should point out that on the site, the published processing time is 20 business days (shipping time not included). I'm thinking if I check it again tomorrow or Monday and it's marked complete, I'd say it's quite possible that they can finish it in less time than what they published.
