Thanks docpak and Islamabad...
Here's the funny thing about what they wrote:
Step 1: Submit the documents listed below to our office in London. (These instructions do not apply to accompanying family members who are entitled to Canadian citizenship, because they will have to travel on their Canadian passports.)
1. Clear photocopies of your passport and the passports of each accompanying family member. The passports must meet the Passport Specifications on page 2 of this letter because these are the passports you will use to travel to Canada.
2. The Updated Information Chart on page 3 fully completed for you and each accompanying family member.
Submit these three items within 45 days of the date of this letter (or the date of the email if you received this by email). All items for you and your accompanying family members must be submitted together in one package.
Mail or courier your package to:
PHEP Processing
Immigration Division
Canadian High Commission
38 Grosvenor Street
London, W1K 4AA
United Kingdom
So they clearly asked for 2 things then wrote 'these three items'... which is confusing, but i'm advised to send a covering letter and only those two items because this seems to be a mistake on their side.
docpak, how long have you been waiting for PPR2 after sending your PPR1 documents? Are you based in Pakistan?
