Validate your forms
Some forms have a “Validate” button, specifically the
- IMM 1344 (Application to Sponsor, Sponsorship agreement and Undertaking)
- IMM 0008 (Generic Application form for Canada) and
- IMM 5669 (Schedule A).
You should fill out your forms on a computer and validate them electronically to make sure you’ve answered all questions. This reduces mistakes and helps you submit a form that is complete. When you click on the Validate button, any missing information will be identified by a pop-up error message or a red square around the fields that need to be completed.
Important: If you are unable to fill out your forms using a computer or are unable to successfully validate your forms, you must provide a written explanation for why you were unable to do so.
After being validated, the IMM 1344 and IMM 0008 will create
barcode pages (see image below).
When you’re preparing your application, place these barcode pages right underneath your checklist.
Note:The IMM 5669 (Schedule A) form
will not produce a barcode page when it’s validated.
this is for Spouse sponsorship but applicable to all other applications i believe. Hope this helps!!
