Quick breakdown, I live in Detroit and wife lives in Windsor. PR app was sent in Aug. I have been crossing the border practically everyday for the past five years, even though it isn't permitted. Recently an officer suggested I go to immigration and ask for a visitor record. I go to immigration and the immigration officer told me that I didn't need one unless I planned on moving there while the PR app was in process. I told him that I would like to move there, but I still needed to go to work in the states everyday. He told me that that was indeed permitted, took down my information as well as my Canadian address and I was issued the visitor record. I now cross over to work everyday and return home to Canada while driving a Canadian plated vehicle. If anyone is in the same position I highly suggest asking for a visitor record.
