I am really worried about my permanent residency file.I am married,living in Canada and my spouse is in India.We applied his visitor visa application while my TR to PR file was under processing.We got request letter of his biometrics for visitor application and later we got another request letter from TR to PR portal for him.The UCI# was same for both applications,we thought we can book one appointment for biometric.VFS officials told my husband to book another appointment for PR,is it really required to book two biometrics and it is so difficult to get appointments in india.Please answer.
