I have done this exactly. Submitted a word doc saying I dont have a rep for my PR profile. Do you remeber what happened with you next?I received a form 5476 request yesterday. I mentioned my spouse name as representative and later removed her name in eAPR. So was wondering why I got the request.
Later I called up CIC call center and spoke to a representative. He confirmed that there is no representative on file and if I do not wish to add anyone, I just write an brief explanation on plain paper and upload the same instead of IMM 5476 form.
So that is what I am doing now.
Any other suggestion?
