Hi
@NS2013 the letter clearly has the following details:
The processing of your application for permanent residence in Canada is almost complete. You must complete the following steps within 30 days in order for our office to issue your Confirmation of Permanent Residence and, if applicable, your permanent residence visa.
STEP 3: PREPARE YOUR DOCUMENTS - And in this section you will be asked to submit your docs - the PPR letter, Passport, photographs, eye color and height, and RPRF fees.
And then the letter will also have this information:
To submit your package while overseas:
Please submit your package to the nearest Visa Application Centre along with the VAC Passport Transmission fee.
The letter will be pretty clear in what it is asking you to do.
