I went to Niagara. Walked down to US, Crossing Canada Border at rainbow bridge. Lady gave a rejection letter to US, though I have US Visa. I specifically asked her if the rejection will leave any mark in the system, she said No. So took the rejection letter and went back to canada immigration. Provided all the PR documents, address proof. They did not ask for my Work permit even. Waited for 15 minutes and thats all. I got my PR formalities completed.
Thanks to the Forum.
