I sent in an application in the mail to extend my father in law's visitor visa for a few more months after it expires on Feb 14th. I did not send by courier (my mistake) so don't know if it was received. From reading online I am under the impression that we will not receive any updates until the decision is made in 110 days. Is there any way to confirm that the application is received? I cannot check online as I have not been given an application number. I am unable to link my paper application online either. My worst fear is the application got lost in the mail and my father in law will be in Canada with no status. Last option would be to apply again online because then you are sure that it is received. What do you think?
