It depends on how old the form is.
We currently accept versions of the application form dated October 2017 or later. You can find the version date on the bottom left corner of the form. For example, “CIT 0002 (01-2019)” means the version date is January 2019. The current version is always available as part of your application package.
If you submitted your application on a form with a version date before October 2017, we’ll return it to you and ask you to resubmit your application using the newest version of the form.
If you used a form dated October 2017 or later and we returned it to you as incomplete, you don’t need use the newest form to resubmit your application. You can resubmit it using the same form once you get the missing information or documents.
