Hi canuck78 I have a question. Is it possible if I submit an application for Canada TRV without Flight Booking and explain that I am not sure that I will receive the VISA. When I already have it, I will book one.
In my place, Students who intend to study in Canada can do the Medical Examination before requested and then submit it in their application in order to reduce the processing time.
You can ask some IRCC authorized clinics in your country.
Maybe the system was congested. That some time happen. As long as you keep the original Biometric Request letter which has sealed after your parents gave their biometric. It will be fine.
