For anyone who has a birthday between their ITA and eAPR, this is not going to affect your application. My birthday is in a few days, so I will be dropping down 5 points but this will not affect my application. I know there has been much debate and confusion on this, so I will quote what my ITA says:
"NOTE: If you had a birthday since we sent you this invitation, and the change to your age decreases your points total, this will not cause us to refuse your application for permanent residence."
"NOTE: If you had a birthday since we sent you this invitation, and the change to your age decreases your points total, this will not cause us to refuse your application for permanent residence."
