They received my application for permanent residence on March 1, 2012, and i am still waiting for medical request.lvladman said:Don't worry, I applied on March 5th and still no news. It is a little bit random.
If you've provided them with your email address, it's gonna be an email, otherwise you will receive a mail. Your ECAS status will also change to "In Process" in few hours after the email.
Good luck
