When filing for 485, one question is the 'last entry to U.S'. I went to Canada a few times by car. When I came back using my H-1B status, I did not get new I-94 or new visa stamp. Do I need to report the date coming back from Canada as my last entry date? I don't have any proof of my stay in Canada since I stayed with some friends and paid cash for everything. Also because I am a Canadian PR, I don't have any temporary visa to prove that I entered Canada on a specific date.
Thank you!
