I'm an international student in the University of Waterloo. I and my wife have been here In Canada for more that 12 months. I have a study permit for 4 years and my wife has a work permit for 4 years. I filled the permanent residence application. My wife is pregnant now. We expect to deliver the baby by November 2010 (after 5 months). She will deliver the baby here in Canada. So, the baby will be a Canadian citizen and does not need to be immigrant. I would like to send my application these days. Do we have to change the application after delivering the baby?
