Here is a copy paste from the PPR1 letter:
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. Two recent photographs of yourself and two recent photographs of each of your accompanying family
members. The photos must meet the Photo Specifications on page 3 of this letter.
3. The Updated Information Chart on page 4 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.
