Hi
I got an email on Jan 20, 2021 for “Biometric reminder Fee” (I didn't attached it with the package because my husband did Biometric on Dec 14, 2020 for Visa extension) I was told by biometrics’ office it’s good for 10 years. BUT I ended up paying Biometric fee same day and sent the receipt via IRCC Webform
