I am a canadian citizen and my current job is ending and so does my TN visa i have. I understand that i need to leave the country within 10 days of my visa expiring.
1 - What do i do when im leaving the country to prove that i've left (hand in the TN visa to the canadian border guards)?
2 - I am currently looking for a new job and hope to get a new TN visa with a different company before the other expires, however if i am unable to, can i return to the US as a visitor for the 6 months im allowed, the day after i leave and hand in my TN visa?
3 - Is it any more difficult to switch jobs and get a New TN visa as if i kept the same job?
