I came India after 5 years for a visit but forgot to get my TRV while in Canada, my lawyer from Canada is my representative so she did all the calls for me. You can make someone a representative from Canada to call for you.
If you receive this error it means they are about to send you the letter of passport submission, they might have missed one last thing to send you the same.
Yes, it just happened with me yesterday after receiving the letter , they said it was sent in error. Did you got the final approval letter?
please advise?
