You been asked to submit full application as over the last two years information with CIC is out-dated about you and your family. No, you are not required to submit any more fees for processing your application. Check your letter again, if CIC is asking to submit "RIGHT OF PERMANENT RESIDENCE FEE" which will be CAD 490 or USD 415 (for principal and Spouse each) and did they attached any fees sechudule with your letter?
CIC did not mention in the letter to submit "RIGHT OF PERMANENT RESIDENCE FEE"; They also did not attach any fees schedule with my letter.
Does it mean that unless specifically mentioned in the letter, we need not send any money? However, the application guidelines at their web site mention about paying the fees. That caused the confusion.
