This does sound quite accurate. received a slip at the VFS office outlining to submit a copy of the passport and pictures.When you got the BIO letter you were to go to a VFS office for Biometrics collection. There is nothing for you to submit regarding that. To me it sounds like you submitted a copy of your PP and the pics the the LVO as if you had received PPR which does not seem to be the case. I think the LVO sent you the letter to say that you have to wait until you get the PPR before submitting the docs that you did. Did you get something from them asking you to submit the copy of the PP and pics?
Does it sound like that might be the case?
They have since followed up saying I need to submit my letter of passport request as well as this "CIC email copy" to continue.
I am yet to receive PPR but still not too sure what the email they're requesting is.
