My I-94 had expired on January 1, 2018. I returned it to the border post ar Rainbow bridge on Feb18th The US officer asked me if I wanted to enter US and I told no, I only want to return the form and drive back to Canada. She filled up a form and allowed me over to join the queue of vehicles returning to Canada from US. I saw that the form that she filled was the refusal to admit form with a handwritten note WD-2 didnt want to come to US. She didnt explain or have me sign anything. I am now worried if this incident is negative for my prospect to reenter US at some point. Please advice
