Thank you very much you have been of help but o try to change my contact but it was asking for UCI or Client Number, do you have any idea on how I will go about that?
If you are the Principal Applicant your UCI can usually be found on past application (like work permits, study permits, etc.) or past correspondence from IRCC.
I used the webform first because i didn't have the application number or UCI with me at the time. The UCI isn't required to fill in the webform.
Under Type of Application/Enquiry, select Change of Contact Information. Then type in the new address, then fill in Applicant details, then Enquirer info.
You can submit another request after you get AOR. The AOR email has the UCI and Application Number.
