Which of the following is NOT a reason for issuing a deficiency notification?

The choice indicating that the applicant's previous work experience is not a reason for issuing a deficiency notification is correct because deficiency notifications are typically concerned with the immediate completeness and adequacy of the application itself. This includes aspects such as whether the application form is filled out entirely, whether the necessary fees have been paid, and whether all required supporting documents have been submitted in a sufficient form.

The applicant's previous work experience is generally assessed in a separate part of the evaluation process and does not directly affect the formal completeness of the application at the time of submission. Therefore, while past experience is important, it does not constitute a deficiency in the application that would warrant a notification.

In contrast, the other reasons listed relate directly to specific tangible components of the application process. An incomplete application, insufficient application fee, or deficient supporting documents can all lead to the application being considered unsatisfactory for processing, which is why they are valid grounds for issuing deficiency notifications.
