Living in the US as a student and will be working on a TN soon. Let's say I get rejected at the POE for whatever reason; can I still enter the US as a tourist/no-Visa status? I'd be doing it cuz my apartment, etc. are all in the US and at the very least, I'd have a return flight scheduled to come back to the US. I'd prefer to re-enter the US and then try again at another Canadian POE (let's assume the error was something with paperwork, etc.)
