ok, since it is like that, just let it be a joking.
I did the test on Sept. 29, and now being asked for a oath appear on Dec. 5, but I have to leave here for my Christmas vacation in China before Dec.5. The only thing you need to do is to check your e-status online in CIC website very offen, and you can postponed your oath date by calling the phone number on that letter sent to you as soon as your receive it or after you find that same information in your status account, Good luck!
