Hi All,
I have the same situation here for my OWP extension. I submitted my inland PR family class(spouse) application in Feb 4 2019 and CPC Mississauga received it 2 days after. I got my AOR in March 28 2019. CIC sent back my OWP permit extension application due to insufficient payment (I only paid $155 WP application fee) and it was sent back to me on April 1st. I paid the missing fee and sent back the same day. Now I am not sure if it did it right coz I sent it back to CPC Mississauga as I did not see any instruction to send it somewhere else. I remember the note says " CPC Mississauaga will not proceed with the application until the fee is paid so I thought to resubmit the OWP application with the correct payments. My current work permit will expire on April 21st and I'm so worried that CPC Mississauga will return my OWP application again for the reason that it was resubmitted to the wrong case office. Need your thoughts re my case and I thank you in advance for your future feedback.
