I have extended my visitor log three times now and I am just about to turn in my PR application via spousal sponsorship. My status expires in April so I will be extending one more time while my app is in processing. I just noticed on the back of my visitor record is says your should apply to extend your stay at least 30 days prior to expiry, but every other time I have extended it, I have waited until a day or two before expiry and it’s been accepted. Is this a new rule that I missed?
