Read your own instruction letter
IRCC’s biometrics guidance explains the instruction-letter and collection-site process. Use your letter to identify the required action and deadline, then use the official site finder. Booking an appointment is free; separate it from any biometrics fee that may apply.
Record three different moments
Keep the date you received the letter, the appointment date and any completion record as separate entries. Add a reminder to check the documents listed in your instructions. This prevents a booking confirmation from being mistaken for completion of the requested step.
Keep a practical follow-up note
If you cannot meet the deadline, read the current official instructions for contacting IRCC and retain evidence of the situation. Do not simply move the date in your personal tracker and assume the official deadline changed. A local reminder does not send a request to IRCC.
