Yes, it is completely acceptable to use the current version of the Schedule A – Background Declaration (IMM 5669) form available on the official IRCC website, as the link provided in your Additional Information Request is an internal IRCC link that is not accessible to applicants. Many applicants encounter this same issue, and IRCC accepts the publicly available version of the form without any problem. Since the personal history section on the form does not provide enough space to include your entire timeline, it is also perfectly fine to continue your personal history on a separate sheet. Make sure the continuation page is clearly labeled with your full name, UCI, and application number at the top, and indicate that it is a continuation of question 8 (“Personal History”) from the Schedule A form. List your activities in chronological order without any gaps, matching the columns from the original form (From, To, Activity, City/Country, and Status). You can type it in a Word or PDF document, and it’s a good idea to sign and date the continuation sheet at the end. Once completed, combine the form and the continuation sheet into a single PDF file and upload it through the link or webform provided in your Additional Document Request. This approach is fully accepted by IRCC and will ensure your response meets all their requirements.
