My status was changed on 21st September.It said information regarding oath was sent to me on 21st Sept.I have not received any email till yesterday.I called CIC and they told me that the oath invitation letter may have been sent by postal mail.The rep informed me the time and address where to attend the oath and also sent em a checklist of documents to take along with me.She also told that I can attend the oath even if don't receive the oath invitation letter on time (advised me to meet the incharge and inform,who can check in the list)
But fortunately,I have received the oath invitation letter through Canada Post today
