The deadline passed and my clients were advised to begin the process again, including payment of all application fees once again.
However, after a request for reconsideration, the Visa officer agreed to allow my clients the opportunity to take their medicals once again. Why is this important? The date an applicant is required to enter Canada is usually one year from the date of the medical exam. Taking another medical exam extends the period of entry another year.
An additional year was sufficient for my clients to arrange their affairs and enter Canada without having to apply again.
