My first set of applications was returned ,as I forgot to send my daughter health card . And I resend just replaceing her form as fresh application with explaining letter. As my and my wife application we’re check and photos were sticked on forms in white small pouch. Second time it was accepted . From m point of view if your application are checked and they mention only to what every is needed please do that only.
Remember if you are crossing 90 days on date change form , if you crossing 6 months in photo changed them .
