I was given 2 years of PGWP because my biometrics are expiring. I asked through webform and they told me give biometrics again and then apply by paper application for extension. Now I don't have a biometric verification letter. I just have one letter of informing me that my biometrics are expiring and you may consider doing it again to apply for extension and it has a bar code. Is that letter enough? I'm in Edmonton. Thanks
