Hello the letter will be addressed to principal applicant only. You have to use the same letter to book an appointment or for passport transmission via courier to Vfs global Canada for any accompanying family member/dependent. Hope this helps.I have checked it before on this forum that people mentioned that they received passport request of Principal applicant only. I got PPR for my father and nothing is mentioned about my mother. Can anyone please confirm if they had issues submitting passport or if VFS will accept both passports with same letter?
