I am from India and landed in canada as an international student. I graduated from school in May 2019 and applied for my post graduation work permit on June 12, 2019. Also, I have a valid study permit until March 2020 but my multiple entry TRV is expired as I renewed my student visa but not the TRV. I need to travel to United States by first week of September by land but my TRV is expired. Can I travel and come back from States while waiting for the post graduation work permit and expired TRV? Please let me know as soon as possible.
